Potter's Wrasse (Hawaii)

Macropharyngodon geoffroyi - Also known as the shortnosed wrasse. A 55 gallon or larger aquarium with peaceful tank mates and well established live rock with a layer of live sand is suitable. It eats small invertebrates (foraminiferans and amphipods) that grow on live rock and is therefore not suited for newly established tanks. The diet should be supplemented with live feeder shrimp and black worms, and frozen preparations for carnivores.

Potter's wrasses are difficult to keep, and should not be tried by an inexperienced hobbyist.
They are designated expert only, and not subject to the 14 day stay alive guarantee.
