Mature females are plumper and usually a little larger than males. The Crystal Red Tetra is an egg-scattering free spawner exhibiting no parental care. Well conditioned mature fish will spawn often and in a mature, heavily planted aquarium it is possible that small numbers of fry may survive. To raise more fry the adults should be separated in a small, dimly lit spawning tank which base is covered with some kind of breeding mesh or with fine-leaved plants to protect the eggs from the greedy parents. The water should be slightly acidic or neutral pH. The fish can be spawned in a small group of one or two males and several females. After they scatter the eggs the adult fish can be removed. After the fry hatch, they can be fed with liquid fry food, and Artemia nauplii or microworm.
