Kyphosus corneliiWestern buffalo bream | Cornel's Drummer | Western Drummer
Localised, Temperate Australasia
More slender body shape than other drummers, inside of pectoral fins orange/yellow and light-edged upper and lower tail margins with dusky bar inside. It occurs in mixed schools with the silver drummer on the west coast. It differs from the silver drummer in having a more forked tail, and lacks the black edge to the tail fin and the moustache-like marking under the eye. Although both species feed predominantly on seaweeds, the diets of the two species differ, the western buffalo bream eating mainly red algae and the silver drummer preferring brown algae.
Max Size: 70 cm
