Found sheltering during the day, over soft silty sand bottoms, dispersing at night foraging for food, over coral reefs.
They feed on small fish, benthic invertebrates and zooplankton.

Males incubate their eggs inside their mouths, as the egg masses increase in size they can be found with wide open mouths where they shift the eggs around to aerate the egg masses. Ref: https://www.fishbase.se/summary/Ostorhinchus-bryx.html
