Description

The standard body length is 34 cm, but sexual maturity can be reached at 29 cm. 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.[1]

Ecology

They feed primarily on aquatic plants, leaf litter, fallen fruit, and seeds.[2]
