What I admire about this five gallon fish tank with filter kit is its size. It's so small and compact it fits any small space. This is very ideal in offices and living rooms. It is also ideal for aquariums that can be put on top of a small desk. I even put one in my kids' rooms, and they're so delighted to see Betta fish every night before they go to bed.

The three-stage filtration system effectively keeps all the unwanted elements out of the water – particles, chemicals, and harmful organisms that could compromise the health of the fish and plants.

There are so many things to like about this product; like the fact that it is easy to assemble. I didn't need to use any special tools just to set its filter up. But I think the top-rated part of this product is its lighting. It keeps the aquarium well-lit which becomes a charming part of the decoration, especially at night.

There are so many things to like about this product. First is the design. I was very impressed that the filter itself was incorporated into the tank. Not all filters can be integrated into the tank itself. This one, however, makes things a whole lot easier. The filter is separated into a small compartment which allows the fish to roam freely without getting interrupted, although the filter looks a bit bulky.

I also commend the wonderful display of LED lights, especially at night. This feature brings out the beauty of the aquarium to a whole new level. I can easily see the condition of the contents of the tank because of the balanced illumination LEDs bring.

Seeing the design of the filter makes me agree on the manufacturers' brilliant marketing strategy. The filter fits perfectly in the tank, therefore reducing any potential drawbacks that other separate products have. Moreover, the filter and the tank are absolutely durable and can withstand accidental bumps without getting compromised.

What I don't like about this product is the uncontrollable flow rate. The flow rate is too strong for my fish. Sometimes I see them getting blown over when they pass through the portion of the aquarium where the water is delivered back to the tank.

Pros
  • Has a terrific three-stage filtration system
  • Has 37 LEDs to illuminate the tank's contents
  • Package includes: BioMax bio rings, foam block, and activated carbon

  • Operates quietly
Cons
  • The flow rate is too powerful for Bettas

It can successfully remove any standing debris or particles, harmful chemicals, and unwanted organisms to keep the water clean and odor-free at all times. Beginners will also love using this filter because it can really take some stress of fishkeeping away from them.

What I don't appreciate about this product, though, is how the LEDs gradually destroy the ornaments inside the tank. The fish thrives with the LEDs on however, it's the opposite when it comes with the plants. The upper portion of my ornamental plants that are near the LEDs withered. I can turn the lighting off, but it would make the aquarium dull.

Pros
  • Has 15 blue LED bulbs
  • Has 1 LED hood
  • Has an amazing three-stage filtration system
Cons
  • Plants start to get a bit flaky after two weeks
To wrap it up, I am confident to say that the Glofish Aquarium Tank Kits with LED Lighting is a great filter for every beginner. Even the seasoned ones are impressed with this one. The package comes with a reliable 5-gallon tank, has 15 mesmerizing LEDs, and an efficient filtration system.

What I don't like about this product is the way it vibrates loudly, especially at night. My son complained about it and had to shut the filter down immediately.

Benefits of owning a 5-gallon fish tank

Owning a 5-gallon fish tank can be a rewarding and enjoyable experience for both novice and experienced aquarium enthusiasts.

One of the primary benefits of a 5-gallon tank is its compact size, making it an ideal choice for those with limited space, such as apartment dwellers or individuals with small homes. Despite its modest dimensions, a 5-gallon tank can still accommodate a vibrant and diverse aquatic ecosystem, allowing you to create a captivating underwater world right in your own living space.

Another significant advantage of a 5-gallon fish tank is its affordability. Compared to larger tanks, 5-gallon setups generally require less initial investment in terms of equipment and supplies, making them an accessible option for those on a budget. Additionally, the smaller size translates to lower operating costs, as the energy consumption for filtration, heating, and lighting is typically less than that of larger aquariums.

Furthermore, a 5-gallon fish tank offers a unique opportunity to experiment with aquascaping and explore the art of creating visually stunning underwater landscapes. With its compact size, you can get creative with the placement of decorations, plants, and hardscapes, allowing you to craft a personalized and visually captivating aquatic environment that reflects your individual style and preferences.

Considerations before buying a 5-gallon fish tank

Before diving into the world of 5-gallon fish tanks, it’s essential to consider a few key factors to ensure a successful and enjoyable fishkeeping experience. One of the primary considerations is the type of fish you plan to keep. While a 5-gallon tank may seem like a small space, there are still several species of fish that can thrive in this size of aquarium, provided you choose them carefully and maintain the tank properly.

Another important factor to consider is the level of commitment and time you are willing to invest in the maintenance of your 5-gallon fish tank. Smaller tanks generally require more frequent water changes, testing, and cleaning to maintain optimal water quality and a healthy environment for your fish. It’s crucial to assess your available time and willingness to dedicate the necessary attention to your aquarium’s upkeep.

Additionally, you’ll need to consider the initial setup costs, which can include the tank, filtration system, lighting, heater, and other essential equipment. While 5-gallon tanks are generally more affordable than larger setups, it’s essential to budget for these expenses to ensure you have everything you need to create a thriving aquatic ecosystem.

Choosing the right location for your fish tank

Selecting the right location for your 5-gallon fish tank is crucial for the overall success and aesthetics of your aquarium. Ideally, you want to choose a spot that is easily accessible, well-lit, and free from direct sunlight or drafts, which can negatively impact the tank’s water quality and temperature.

When it comes to placement, it’s best to choose a sturdy, level surface that can support the weight of the tank, water, and equipment. This could be a dedicated aquarium stand, a sturdy table, or a piece of furniture designed specifically for housing an aquarium. Avoid placing the tank near windows, air vents, or other sources of temperature fluctuations, as these can disrupt the tank’s stability and create challenging conditions for your fish.

Another important consideration is the visibility and accessibility of the tank. Placing the aquarium in a prominent location, such as a living room or entryway, can allow you and your guests to enjoy the mesmerizing underwater world it creates. At the same time, ensure that the tank is positioned in a way that allows for easy access during maintenance and feeding times, making it convenient to care for your aquatic pets.

Essential equipment and supplies for a 5-gallon fish tank

Equipping your 5-gallon fish tank with the right gear and supplies is crucial for creating a thriving and sustainable aquatic environment. The essential components you’ll need to consider include a quality aquarium, a reliable filtration system, appropriate lighting, and a suitable heater.

When it comes to the tank itself, look for a well-constructed, tempered glass or acrylic aquarium that is specifically designed for a 5-gallon capacity. These tanks are often available in a variety of shapes and styles, allowing you to choose one that complements the aesthetic of your living space.

The filtration system is a critical component, as it helps to maintain water quality by removing waste, debris, and harmful toxins. For a 5-gallon tank, an efficient hang-on-back (HOB) or internal filter is often the best choice, as they provide adequate filtration without taking up too much space.

Appropriate lighting is also essential for the health and well-being of your aquatic inhabitants. Opt for an LED or fluorescent lighting system that is specifically designed for aquarium use, as it will provide the necessary spectrum of light to support the growth of aquatic plants and ensure the overall vibrancy of your underwater ecosystem.

Finally, a reliable heater is necessary to maintain a stable and comfortable water temperature for your fish. Look for a submersible heater that is specifically sized for a 5-gallon tank, ensuring that it can effectively regulate the water temperature and create an optimal environment for your aquatic pets.

Setting up and cycling your 5-gallon fish tank

Setting up and cycling your 5-gallon fish tank is a crucial step in establishing a healthy and thriving aquatic environment. This process involves several key steps that will ensure the long-term success of your aquarium.

Begin by thoroughly cleaning the tank, decorations, and any other equipment you plan to use. Rinse all components with dechlorinated water to remove any residues or contaminants that could harm your fish. Next, carefully arrange the tank’s substrate, plants, and decorations, creating a visually appealing and functional layout that will provide hiding places and enrichment for your aquatic inhabitants.

Once the physical setup is complete, it’s time to fill the tank with dechlorinated water and install the filtration system, heater, and lighting. Ensure that all equipment is properly functioning and that the water temperature is within the recommended range for the fish species you plan to keep.

The final and most crucial step in setting up your 5-gallon fish tank is the cycling process. This involves establishing a stable and beneficial bacterial colony that will help to break down harmful waste products and maintain the overall water quality. The cycling process can take several weeks, during which you’ll need to closely monitor water parameters and perform regular partial water changes. Be patient and diligent during this stage, as a properly cycled tank will provide a solid foundation for the long-term health and well-being of your aquatic pets.

Selecting the right fish for your 5-gallon fish tank

Choosing the right fish species for your 5-gallon fish tank is essential to ensure the success and longevity of your aquarium. While a 5-gallon tank may seem small, there are several fish species that can thrive in this compact environment, provided they are selected and cared for properly.

One of the most popular choices for a 5-gallon tank is the betta fish, also known as the Siamese fighting fish. Bettas are known for their vibrant colors, long, flowing fins, and relatively peaceful temperament, making them an excellent option for a small aquarium. However, it’s important to note that bettas are territorial and should not be housed with other male bettas or certain aggressive fish species.

Another suitable option for a 5-gallon tank is the dwarf gourami. These small, colorful fish are peaceful and can coexist with other compatible species, such as small tetras, rasboras, or corydoras catfish. Dwarf gouramis are also known for their interesting behavior and can add a unique visual element to your aquarium.

For a more diverse community tank, you may consider a group of small schooling fish, such as neon tetras, cardinal tetras, or ember tetras. These vibrant, active fish thrive in small groups and can create a mesmerizing display in your 5-gallon aquarium. Just be sure to choose species that are compatible in terms of size, temperament, and water parameter requirements.

When selecting fish for your 5-gallon tank, it’s crucial to research the specific needs and care requirements of each species to ensure they can thrive in the available space and water conditions. Overstocking or choosing incompatible fish can lead to stress, aggression, and poor water quality, so be mindful of the tank’s limitations and choose your inhabitants accordingly.

Feeding and caring for your fish

Proper feeding and care are essential for maintaining the health and well-being of your fish in a 5-gallon tank. Establishing a consistent feeding routine and paying attention to the specific dietary needs of your aquatic pets will help ensure their longevity and the overall success of your aquarium.

When it comes to feeding, it’s important to avoid overfeeding, as excess food can lead to water quality issues and potential health problems for your fish. Opt for a high-quality, balanced fish food and feed your fish small, frequent meals, rather than large, infrequent feedings. Carefully monitor your fish’s appetite and adjust the feeding amount accordingly, ensuring they consume all the food within a few minutes.

In addition to feeding, regular water changes are crucial for maintaining water quality in your 5-gallon tank. Depending on the number and type of fish, as well as the overall bioload, you may need to perform partial water changes of 25-50% on a weekly or bi-weekly basis. This will help to remove accumulated waste, replenish essential minerals, and keep the water parameters within the optimal range for your aquatic inhabitants.

Alongside water changes, it’s essential to monitor and maintain other water quality parameters, such as pH, temperature, and ammonia levels. Use reliable testing kits to regularly check these parameters and make any necessary adjustments to ensure a healthy and stable environment for your fish.

Regular cleaning and maintenance of the tank and its equipment are also vital for the long-term success of your 5-gallon aquarium. This includes tasks such as cleaning the glass, removing algae, and maintaining the filtration system to ensure optimal performance and water quality.

Maintaining water quality in your 5-gallon fish tank

Maintaining water quality is crucial for the health and well-being of your fish in a 5-gallon tank. Due to the smaller water volume, water parameters can fluctuate more quickly, making it essential to stay vigilant and proactive in your maintenance efforts.

One of the most important aspects of water quality is the nitrogen cycle, which involves the conversion of harmful ammonia and nitrite into less toxic nitrate. This process is facilitated by beneficial bacteria that colonize the tank’s substrate, decorations, and filter media. Regularly testing for ammonia, nitrite, and nitrate levels and performing timely partial water changes can help to keep these parameters in check and prevent any spikes that could be detrimental to your fish.

In addition to the nitrogen cycle, it’s essential to monitor and maintain other water quality parameters, such as pH, temperature, and dissolved oxygen levels. These factors can significantly impact the overall health and behavior of your aquatic inhabitants, so it’s crucial to ensure they remain within the optimal range for the specific fish species you have chosen.

To help maintain water quality, consider incorporating live plants into your 5-gallon tank. Aquatic plants not only add visual interest and natural beauty to your aquarium but also help to absorb excess nutrients, produce oxygen, and provide hiding places for your fish. Carefully select low-light, low-maintenance plant species that are well-suited to the size and lighting conditions of your 5-gallon setup.

Regular water testing, partial water changes, and maintaining a balanced ecosystem are all essential for ensuring the long-term success and water quality of your 5-gallon fish tank. By staying proactive and diligent in your maintenance efforts, you can create a thriving and visually stunning underwater world for your aquatic pets to thrive in.

Troubleshooting common issues with 5-gallon fish tanks

While 5-gallon fish tanks can be incredibly rewarding, they can also present unique challenges that require prompt attention and troubleshooting. By being aware of the most common issues and how to address them, you can ensure the continued health and well-being of your aquatic inhabitants.

One of the most prevalent issues in small tanks is water quality problems, such as spikes in ammonia, nitrite, or nitrate levels. These can be caused by overfeeding, overcrowding, or inadequate filtration and water changes. To address these issues, be diligent in your water testing, perform more frequent partial water changes, and ensure that your filtration system is functioning correctly.

Another common problem in 5-gallon tanks is temperature fluctuations. Due to the small water volume, the tank’s temperature can be easily affected by changes in the surrounding environment, such as drafts or direct sunlight. Invest in a reliable heater and monitor the temperature closely, making adjustments as needed to maintain a stable and optimal environment for your fish.

Algae growth can also be a challenge in small aquariums, as the limited water volume can quickly become imbalanced, leading to excessive algae blooms. Combat this by introducing live plants, reducing lighting duration, and performing regular tank cleanings to remove any accumulated algae.

Finally, be mindful of the potential for aggression and territorial behavior, especially when housing certain species like bettas or cichlids in a 5-gallon tank. Observe your fish closely and be prepared to make adjustments, such as rearranging decorations or removing aggressive individuals, to maintain a peaceful and harmonious community.

By being proactive in your troubleshooting efforts and addressing any issues promptly, you can ensure the long-term success and enjoyment of your 5-gallon fish tank. Remember, a little diligence and attention to detail can go a long way in creating a thriving underwater ecosystem in your home.

Frequently Asked Questions

Amoskeag-Fishways-FAQs

Is a 5 gallon tank big enough for 2 fish? 

It’ll depend on the type of fish inside your 5-gallon tank. But in most cases, a 5-gallon vase or tank will be fine with holding two small fish. For instance, I could see it being an excellent situation to keep two minnows.

If you want a more precise measurement, use the one-inch per gallon size comparison rule. For example, someone with a 5-gallon tank should only have fish up to 5 inches long. These 5 inches could be from one single fish or two.

A modern option like Marineland ML90609 Portrait Aquarium Kit would be an excellent choice for two fish. Its measurements provide everything necessary to give them a comfy environment. Plus, this small fish tank with filter and light included is easy to set up for newbies.

However, I wouldn’t look to fit two fish in my 5-gallon or even a 10-gallon tank. I have a betta fish that isn’t a species known for playing well with others. So if you want a 5-gallon tank for betta fish or larger species, don’t test your luck.

What fish can go with a betta in a 5-gallon tank?

Placing any fish with bettas isn’t one of the smartest ideas. Sadly, bettas are known for their aggression and tendency to attack other fish with reckless abandon. It often leads to them killing the other fish rather quickly.

But you can limit these occurrences by choosing less aggressive fish. In doing so, there’s a much higher likelihood of your betta not becoming territorial over the tank. A solid example would be an ember tetra, which isn’t known for being aggressive.

However, I’d still steer clear of housing a betta with any fish unless absolutely necessary. It’s most suitable to keep them alone inside the dimensions of a 5-gallon fish tank. Trust me; it’s just not worth the potential consequences.

How long do you have to wait to put fish in a 5 gallon tank?

Any 5-gallon tank will need at least 48 hours to achieve ideal conditions. It doesn’t matter if it’s from a top brand like Top Fin or a subpar one: you’ll need to let the tank run with all components set up for a sizable amount of time before adding your fish.

Some experts even suggest waiting a week. I followed this recommendation with my 5-gallon circle fish tank when I first bought it. It allowed me more than enough time to create a suitable environment for my brand-new betta fish.

What are the most trusted 5 gallon aquarium brands?

There are several aquarium brands available today, but there are several more preferable ones of course. These are:

  • Koller Products
  • MarineLand
  • Fluval
  • Marina
  • Tetra
  • Penn Plax
  • GloFish

Most of these products I have tested and mentioned above.

How big is a 5-gallon fish tank?

The typical fish tank has a length of 16 to 18 inches, a width of 5 to 8 inches, and a height of 10 inches. However, some makers like to innovate by creating cube ones, vertical ones (tall and narrow), even curved ones. So the size depends on the style. But it's the smallest filtered aquarium that can fit on your side desk.

What fish can live in a 5-gallon tank?

There are several types of good fish for 5 gallon tank. Full-grown fishes that are small to medium in size (1 – 5 inches long) can fit and live in this small tank. I have my bettas for this, but you would also often see paradise fish, clownfish, killifish, puffer, gourami, crayfish, loach, livebearer, gourami, or fighting fish in some other 5-gallon tanks.

How many fish can I put in a 5-gallon tank?

Again, the rule of thumb is one inch of fish for every gallon of water. So depending on the size of your fish, you'll have: 5 one-inch ones, or 2 two-inch ones plus 1 one-inch fish, or 1 five-inch fully grown fish for your 5-gallon tank. This may seem an easy ratio, but you also must account for the total allowable space for the fish to grow.

Try to estimate first all the dimensions of the materials (e.g. ornaments, filters, pumps, etc.) that you will set up inside the tank. Once you have an idea of what you'll put in, you may deduct the space that these will occupy from the total capacity. From there, you may know the number of fish you can put so as not to make the aquarium too crowded.

Fish may be harmed by their wastes, too. Since they too have by-products, it is important to take note of the frequency and amount. The wastes should be easily cleaned by the filters and should not stay long in the water. So, try to put one or two fishes first, then add the other fishes once you're sure the unwanted products can be cleaned properly.

What fish tank equipment do I need for my 5-gallon aquarium?

There are things that I wish I had known before I decided to keep fish as pets. I should have not bought a lot of unnecessary things for the aquarium. Here's a list of the important equipment and materials:

  1. Filtration system – Choose one that is reasonably priced and can support your fish's needs
  2. Stand or Table – Support for your aquarium is a must.
  3. Fishnet or mesh – You can use this as a cover.
  4. Siphon – I use this whenever there's a need to adjust the volume of water or when I had to get something that is deep down the aquarium.
  5. Scrubber – This one's to clean the built-up algae around the tank.
  6. Thermometer – If you are planning to breed them or if you have a fish that is sensitive to temperature, a thermometer can come in handy.
  7. Heater – This is useful mostly during winter.
  8. Light – this helps illuminate the aquarium at night.

There are some other things that you might put in the tank and buy, but they're not really equipment. You can add gravel, plants, water conditioner, and even figurines.

How to setup and use?

It really depends on the aquarium you opt to buy. If you purchase an aquarium kit, make sure to follow instructions included in the kit. Setting up is pretty standard though:

  • Clean the aquarium first
  • Prepare the water for at least 12 hours
  • Prime the equipment (filters and pumps) by running water through it
  • Fill the tank with the prepped water
  • Decorate the tank
  • Add the fish!

How to care and clean?

There are two ways to maintain and clean a five gallon aquarium: with weekly water change, and deep cleaning for every two to three weeks.

Weekly water change

Tank owners are expected to remove some of the dirty water and replace it with the same amount of clean water. You can remove 25% to 50% of the dirty water. Make sure you prep the clean water first by making it stand for 12 to 48 hours.

Deep cleaning

This must be done every two to four weeks. This is important so as to prevent algae and waste build-up that will not only be unpleasant to look at, but also toxic for the fish. Some algae are alright, but too much of it can also be bad.

The steps to do a deep cleaning are as follows:

  1. Get some of the original aquarium water and place it in a container which will temporarily house the fishes. About 30% of aquarium water is fine.
  2. Turn the filter off and remove it, then carefully remove tall decorations so as not to stir the water too much and to prevent stressing the fish.
  3. If you're using a pump, move it to the temporary container. Carefully remove the fish and place them on their temporary home while you clean the aquarium.
  4. While the tank still has water, scrub the sides to remove some of the algae and waste buildup. If you like to leave some algae, that is fine. Make sure that it does not overtake the tank, though.
  5. Siphon the old water out.
  6. Vacuum the gravel.
  7. Fill the tank with clean water that has been prepped for 12 to 48 hours. Don't fill it to the brim as you will place the fish back together with the old aquarium water. This is so as not to stun the fish and help them adjust to the new clean water better.
  8. Alternatively, if you don't have time to prep the water for at least 12 hours, use a water conditioner. A water conditioner neutralizes chemicals in the water.
  9. Replace the decorations, pump and filter.
  10. Reintroduce the fish by pouring the contents of the temporary container into the aquarium so you place the remaining old aquarium water back.

Don't wait for your tank to see visible signs of dirt before doing a deep cleaning. Instead, create a schedule between two to four weeks, or else you'll pay for it by having unhealthy, or even dead, swimmers.
