These are fish that get along well with other fish, like danios, tetras, Corydoras, mollies, guppies, and swordtails.
These fish can be kept with fish of equal size without becoming overly aggressive, such as the barbs, gouramis, and angelfish.
These fish must be kept singly or in pairs, such as the jewelfish, oscars, and male betas.
