In some places, this species is sympatric with M. poecilus. Occurs in the main bed of streams and appears not to be present in the lower part of rivers. Hides under rocks and decaying wood during the day, its disruptive color pattern helping to disguise it in the environment. Feeds on larvae and pupae of Chironomidae. The originality of its features and its small size make it interesting for the aquarists (Ref. 35381).
