Description

The standard body length is 34 cm (13 in), but sexual maturity can be reached at 29 cm (11 in). The distinguishing feature of the species is the occurrence of a black mid-lateral line running along the lateral line, similar to L. rubripinna. However, unlike L. rubripinna, this black line does not fade or disappear as the fish reaches maturity.^[2]

Ecology

They feed primarily on aquatic plants, leaf litter, fallen fruit, and seeds.^[3]
