📖 Overview

Occurs at the uppermost reaches of mountain streams surrounded by dense natural vegetation; preferring sandy bottoms with gravel or pebbles, where it hides under rocks and stones. It is syntopically distributed together with L. echigonia in the Yura and Kako rivers, although L. echigonia has a tendency to inhabit more lentic waters in swampy streams and ditches .
