Laetacara

Laetacara is a small genus of cichlids native to freshwater habitats in tropical and subtropical South America, ranging from the upper Orinoco River basin in Venezuela to the Paraná River basin Argentina. The genus is also collectively known as the smiling acaras. Like all cichlids, Laetacara species have well-developed brood care.

All members of the genus are monogamous, open spawning cichlids. They are popular in the fishkeeping hobby and are frequently kept in aquariums. Laetacara are relatively small cichlids, growing to about 4-12 cm in length depending on exact species, and are part of the group known to aquarists as dwarf cichlids.
