Breeding

An egg scatterer that spawns among fine plants or mops in soft, slightly acidic water. Adults eat the eggs, so remove them after spawning; it is rarely bred in home aquariums.

Good to know

Some fish sold under this name may be related Moenkhausia species, as the group is taxonomically muddled. May nip long-finned tankmates if kept in too small a group.
