To Reef Tank:
Six Line Wrasse (Pseudocheilinus hexataenia)
Spotted Hawkfish (Cirrhitichthys aprinus)
A Six Line Wrasse is a busy body fish, swimming about the tank inspecting everything. They are moderately aggressive, believing everything is their territory. They do tolerate other species fairly well though.
The Hawkfishes lack a swim bladder, and sit camouflaged on branches of coral, propped up on their pectoral and caudal fins waiting for food to swim by. When it does, they dive on it like a hawk, thus their moniker.
