Ring-tailed Cardinalfish

Found in schools, during the day hiding in coral and rock holes, or under ledges, dispersing at night hunting for food, over coral and rocky reefs. Forming mixed schools during summer and autumn.
They feed nocturnally on benthic and planktonic crustaceans.

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.
