Three-spot wrasse
Halichoeres trimaculatus
This wrasse reaches up to 12 cm and has an elongated body of variable color (green, brown, reddish) with three distinctive black spots on the upper side. Males are more colorful than females. It is diurnal and constantly sifts through sand in search of prey. It is a protogynous hermaphrodite. It can be territorial, especially towards conspecifics. It is known to 'clean' other fish by removing parasites. In aquariums, it needs a sandy substrate to bury itself at night.
