Frequently Asked Questions


What fish are good with goldfish?

Goldfish are known for being social among other aquatic species. As a result, owners can expect them to mesh well with many fish. But if I had to create a list of best goldfish tank mates, it’d start with these five:

  1. Zebra Danio
  2. Japanese Rice Fish
  3. Platy Fish
  4. Rosy Barbs
  5. White Cloud Mountain Minnows

But you don’t have to put other fish with goldfish. Goldfish mesh well with other goldfish, so there’s no reason not to pair them together. In fact, they’re known for schooling, which promotes more exercise and better health.

Conversely, goldfish don’t fare well with tropical or aggressive fish. So I wouldn’t suggest placing them with betta fish, even in a large tank. It’ll only anger your betta fish, causing them to attack the goldfish.

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

Most experts recommend following a rule of one inch of fish per gallon of water. It may sound a little complicated, but it couldn’t be simpler. So basically, if you have a 5-gallon tank, it can hold a total of 5 inches of fish.

In any case, a 5-gallon tank is usually deemed a small aquarium for goldfish. It may not even be enough for a single fully grown goldfish, considering these fish are often between 6 and 8 inches.

As a result, a person with a big goldfish of 8 inches shouldn’t buy a 5-gallon tank. It wouldn’t be able to meet the needs of their larger fish. So instead, these people need a tank of at least 8 gallons. I’d suggest looking into 20-gallon goldfish tank setup ideas because these fish like having friends.

An excellent choice would be Tetra 20 Gallon Complete Aquarium Kit. This fish tank for goldfish with a filter offers another 12 inches of fish to fit into it. Plus, it’s one of the more beautiful goldfish aquariums available.

How often should I change goldfish tank water?

The recommended amount is changing 15% of the tank’s water every week. It’ll help protect the good bacteria within your tank and keep from changing the fish’s habitat too drastically. But this weekly 15% rule is only a guideline, as it can change based on certain factors.

For instance, the size of your tank setup for goldfish and the number of fish will play a role. A good example would be my massive 50-gallon octagon tank. In this situation, I need to change out 15% of the water bi-weekly to ensure the various fish species continue to live comfortably.

What are the most trusted fish tank brands for goldfish?

As for the most credible and trustworthy goldfish tank brands, the following brands are just a few of the world’s most trusted manufacturers that have been in the marine field for a very long time:

  • Tetra
  • MarineLand
  • Hagen
  • Aqueon
  • Aqua Culture

Hence, if you would like to end up getting the smartest investment when it comes to goldfish tanks, the aforementioned brands are outstanding selections for you to look into.

Acrylic vs Glass Fish Tank: Which one is better?

Both acrylic and glass are generally utilized for fish tanks. In reality, at initial glance, it would be tough to notice the distinction between these two materials since both of them are quite transparent and are adept at holding significant amounts of water.

And, it is not till you literally own each form of fish tank that the distinctions become more noticeable.

As for the cost, acrylic is more costly than glass. Acrylic is more prone to getting scratched than glass. Acrylic comes lightweight while glass is slightly bulky. When it comes to shapes, acrylic comes in different shapes while glass comes with limited shapes only.

And, talking about these material’s resistance to impact, acrylic comes with better impact resistance than glass. And, for clarity, acrylic turns yellowish as it gets older while glass retains its constant clarity.

So, now that you have learned the clear distinction of both materials, the decision is yours. As you can see, both of them come with pros and cons.

How many gallons does a goldfish need? What size tank do I need for 2 goldfish?

For comet goldfish or common goldfish, it is highly suggested to consider getting a fish tank that measures a minimum of four feet in length and must come with a volume of a minimum of thirty to fifty gallons. When it comes to sheltering your goldfish, the rule of thumb here is the bigger, the better.

Meanwhile, if you are thinking of keeping more than one goldfish in your aquarium, then see to it to add an additional twelve gallons for every fish is added in the tank.

How to set up?

Here are the guides when setting up your goldfish tank:

  1. Make sure to keep the aquarium away from any sources of heat or windows.
  2. Tidy the aquarium to get rid of any dust that has accumulated while being stored. Afterward, add a layer of gravel or sand. If you decide to utilize gravel, pick the one that comes with grains bigger than a pea. Smaller ones can be hazardous to
  3. As you set up your equipment, never turn anything on yet. Carefully fill the aquarium with de-chlorinated water and after that, you can safely add some tank adornments and plants.
  4. Finally, turn the equipment on and let it cycle for roughly four by up to six weeks long. Take note that it is critical to completely cycle the aquarium as this will help promote a good bed of bacteria to accumulate- this will be in charge of the nitrites and ammonia present in the aquarium.

How to care & clean?

It is imperative to organize a maintenance schedule for tidying up your goldfish aquarium. This is primarily because there would be some tasks for you to execute on a daily basis and other tasks require weekly or monthly maintenance.

Things you need to execute on a daily basis:

  • Feed your goldfish.
  • Check your goldfish for any problems.
  • Inspect the water temperature.
  • Get rid of any huge chunks of unconsumed fish food.

Things you need to execute on a weekly basis:

  • Tidy up the gravel using a siphon.
  • Execute water replacements (should be 25%)
  • Eliminate algae accumulation with the aid of an algae magnet
  • Examine if the equipment is not damaged or operating properly
  • Carefully wipe down the exterior surface

Things you need to execute on a monthly basis:

  • Trim the plants you added inside the goldfish tank
  • Examine the water‘s nitrates, nitrites, ammonia and pH level
  • Replace the filter as per the manufacturer’s guidelines

It is fundamental to strictly adhere to the caring, cleaning and maintenance procedures if you want to keep your goldfish tank in the most suitable possible condition.
