Facts about this animal
The blue puller is a small coral fish reaching a length of 9 cm. The overall body colour is greenish with a light bluish-green sheen to the scales and a blue line from eye to snout.
"Blue pullers", as they are called in parts of their range, are reef-dwelling fish often forming large groups that swim above branching corals (Acropora spp.). Juveniles stay close to individual coral heads and when threatened quickly retreat in the safety of the coral branches.
Blue-green damselfish breed on sand and rubble. The males prepare a nest for spawning which they share with several females. Large number of eggs are spawned, hatching in 2-3 days. The male guards the nest ventilating the fertilized eggs with its caudal fin and feeding on those eggs which do not hatch. Otherwise, green-blue damselfish feed on phytoplankton.

Blue-green damselfish are not an endangered species but their habitats, coral reefs, are threatened in many places. They are thus presented by zoos and aquariums as an ambassador species for reef protection.
