Threespot Damselfish
The threespot damselfish (or Dascyllus trimaculatus), also known as the threespot humbug or domino damselfish, is a widespread species found throughout the tropical Indo-Pacific region from the Red Sea and East Africa to Hawaii, Japan and northern Australia. It typically inhabits coral reefs and lagoons.
This species is easily recognised by its dark grey to black body marked with three distinct white spots, one on the forehead and one on each side of the upper body near the dorsal fin.
Threespot damselfish usually grow to about 10 to 13cm in length and weigh 30g to 45g.
