Nano fish are fish that grow less than two inches and are suitable for aquariums as small as 5 gallons. The amount of fish that an aquarium can safely support is relative to the level of filtration, maintenance, and feeding. Many nano fish are schooling or shoaling species, so be sure to consider this when deciding how to stock your tank. For example, an established, well-filtered 5-gallon aquarium could likely support one school of 6 Celestial Pearl Danios or any of the rasboras we offer, but it could not support multiple schools. With one school of the aforementioned fish, the tank could also support a few scavengers such as nerite snails, assassin snails, and/or a small school of 3-6 Pygmy Coradoras or Asian Stone Catfish if the aquarium is well maintained. Live plants will of course help dramatically when it comes to maintaining the best possible water quality.
