How to Choose Compatible Fish

When selecting fish for your 20-gallon aquarium, consider their size, personality, and care needs. Begin by researching the adult size of the fish you want. Secondly, have a look at the temperament of the species. You would want to avoid pairing aggressive fish.

If you want fish to thrive together, the following should match:

  • Care levels
  • Water temperature
  • pH level
  • Type of foods

Selecting fish that can cohabitate with one another will allow you to create a peaceful and attractive underwater neighborhood.

Tips on Setting Up the Tank

Setting up a 20-gallon tank for community fish is relatively easy with some guidelines. Make sure it sits on a solid 20 gallon aquarium stand. Fit a high-quality filter to maintain crystal clear water, and heat the water if necessary to keep it at the correct temperature.

Use aquarium gravel or sand for the substrate, providing hiding spots and decorating the tank with live or artificial plants. Afterward, fill the tank with dechlorinated water and leave it cycling for a few weeks to increase the good bacteria. Now, slowly add your fish to keep your tank’s ecosystem manageable. There you have it, it’s that easy!

Feeding Guidelines

Feeding fish is very important for their health.  Feed your fish a good-quality flake or pellet for community fish. Occasional treats such as brine shrimp or bloodworms also help to diversify their nutritional intake. Do not overfeed. Feed them what they can consume in a few minutes to prevent water pollution.

Being in charge of a fish community is always challenging and often requires much attention. Here is how to care for them. First, you do weekly water tests to ensure all of the parameters are suitable for your fish. For example, nitrites, ammonia, and nitrates should all be at zero or near zero.

Clean this tank by removing leftover foods and debris from the substrate. Also, please look for any signs of stress, illness, or other changes in their swimming behavior and appearance. Vigilance is important!

FAQs

How many fish can I keep in a 20-gallon tank? 

The general rule of thumb is an inch of fish per gallon of water. However, the ratio for each species could be different. The goal is to create a pleasant and healthy environment with 10-15 small—to medium-sized community fish.

How Do You Clean A 20-gallon Tank? How many times?

To maintain clean and detoxified water, clean weekly. Be sure to clean the substrate (sand) and the decorations every month, and keep the filter clean by examining it frequently.

A 20-gallon tank can allow tropical fish and cold-water fish to be together

Cold-water and tropical fish cannot be kept together because most cool-water fish require warmer temperatures and will not last under the same conditions as tropical fish. Transferring species between cages is never ideal or straightforward, and keeping species that require the same care is best.

What do you do if your fish gets sick?

If your fish are sick, they should always be placed within a quarantine tank to ensure the disease doesn’t spread. To combat the bacterium in your anemone tank, check your water parameters and treat your tank with the appropriate medication. If the symptoms last a long time, consult with a veterinarian.
