Gon's Cardinalfish

Found in dense schools hovering above rocky outcrops, amongst mangroves, entering rivers and in deeper waters with shipwrecks, in silty conditions of coastal reefs.
They feed nocturnally on fish eggs, fish larvae, shrimps and pelagic worms

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.
