Weedy Cardinalfish

Found singly or in small schools, during the day sheltering around algae covered rocks, dispersing at night to feed, over silty mud and sand substrate, of quiet bays and estuaries.
They feed nocturnally on crustaceans 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.
