The Staghorn Damselfish is native to reefs from Malaysia to the Great Barrier Reef. It is so named as
it is associated with staghorn coral (- sorry for those who hoped to see a fish with antlers).
Its appearance is variable with often a green or yellowy base colour, it has visible scaling on the body
and many have vertical shaded bars. It reaches up to 11cm long.
It eats algae and plankton. Eggs are laid on the underside of coral. As common with Damselfish, the male is territorial and aggressive
and will protect the eggs until they hatch.
