Labroides phthirophagus -The Hawaiian cleaner wrasse is a great worker fish in aquariums. They pick and clean off pests and parasites off larger fish going so far to even create specific cleaning stations. As wild caught this species is notoriously difficult to keep in captivity because they don't adapt well to aquarium life and they don't like to eat prepared foods, instead preferring to clean large fish. It's also difficult to know the age of a wild adult and if it is at the end of its lifespan. Captive breeding solves these problems. Our Biota Cleaner Wrasse eat a variety of prepared pellets like EasyReefs DKI pellets and frozen foods. Being born in captivity they're well adapted to aquarium life, and we know the exact age of these young fish so they will live their full lifespan in your tank. They do not require a sand bed, but instead create a mucus cocoon for nightly sleeping. Be sure to provide an escape-proof lid, since these fish will actively search for gaps in the aquarium's cover to jump out. We recommend introducing new fish with an acclimation box. They do not require a deep sand bed but create a mucus cocoon for nightly sleeping.
