📖 Overview

This species forms small schools which are sometimes mixed with T. tevegae. The fishes hover in caves, recesses or under the overhangs of coral reefs. When hovering, the ventral side faces the nearest substrate surface (e.g. the wall or roof of a cave) the same as with T. tevegae. However, T. flavatrum tends to be found more towards the back of the caves and recesses .
