How to Choose Livestock for Your Community Aquarium

There are many fish in the sea, so the saying goes, but when you are stocking a community aquarium, you need to know which ones will make the best pets for your family and be compatible with one another. When deciding which kinds of fish will live together in your aquarium, it’s important to select species that have similar temperature requirements, exhibit comparable behavior, and occupy different swimming levels in the tank.


Before you begin choosing the fish for your community aquarium, have a clear idea of what you want your fish tank to look like. The goal of a community tank is a healthy, stress free environment for a variety of species, and for your aquarium to be arranged in a way that provides beauty and pleasure for you and your family. While any size fish tank can be used as a community tank, the larger the aquarium the more species and amount of fish you can have.


Most freshwater community species can be placed together. Guppies, angel fish, tetras, danios, and Dwarf chichlids (not African cichlides) coexist nicely and eat the same food. All schooling fish should be kept in schools of six or more of each species. It’s best to stay away from aggressive freshwater fish such as Tiger barbs, sharks, eels, and many cichlids, especially if you’re new to community aquariums, because these fish need special attention, caution, and care to ensure everyone gets along well. Bettas should never be placed in a community tank, and don’t put live bearer males and females together unless you want baby fish!
