Pomacentrus tripunctatus (Cuvier, 1830).

Abstract

Pomacentrus tripunctatus or Threespot Damsel is a small tropical species that occurs in shallow coral reef waters. A shallow water species, solitary, in holes of small rocks on sandy bottom with coral rubblesو usually alone. P. tripunctatus is found in shallow bays and silty coastal reefs and other 'dead' areas, up to 3m deep. We report for the first time from Persian Gulf (Kish Island, Iran). Maximum length is 7 cm in Persian Gulf. They found at depths of from 2 to 6 m (in Kish Island, Iran). Adults inhabit shallow bays, silty coastal reefs and harbors with sparse coral and algal growth. Adults are brownish with darker scale margins. They have a large dark spot on the upper caudal peduncle. Juveniles are lighter in color and have a large, blue-margined black spot on the dorsal fin. P. tripunctatus is Oviparous, distinct pairing during breeding. Eggs are demersal and adhere to the substrate. Males guard and aerate the eggs.
