Domino Damsel Dascyllus trimaculatus

The Domino Damselfish, also called the Threespot Dascyllus, is native to coral reefs in the Indo-Pacific. When it is younger, it has three clear white spots on its black or charcoal grey body, one on each side and one on the forehead.

As it grows older, the spots reduce; the one on the forehead goes completely. It grows to 13cm long and is aggressive to other fish. It eats algae and zooplankton.
