Threespot damselfish
Pomacentrus tripunctatus

Family Pomacentridae
updated Aug 10
Where seen? This dark fish with dark spots is sometimes seen on some of our shores among coral rubble and near living reefs. Elsewhere, it is found in shallow bays and silty coastal reefs and other 'dead' areas, up to 3m deep. Usually alone, in holes of small rocks on sandy bottoms with coral rubble.

Features: To about 20cm, those seen about 12-15cm long. Dark grey with a black spot on the upper tail base. Juveniles (as tiny as 2-3cm) may have a black spot on the soft parts of the dorsal fin and blue lines on the head and back (although these little fishes may also be the juveniles of Pomacentrus cuneatus which is also commonly encountered in deeper waters).

What does it eat? It eats mainly seaweeds growing on the sea bottom.
