Common names for the Crescent-Masked Butterflyfish include: The Crescent-Masked Butterflyfish, Raccoon Butterflyfish and Lunule butterflyfish. They are commonly found in coral reefs throughout Africa, Fiji, Indonesia, Maldives, and Tahiti.
These beautifully coloured fish are not considered reef safe. Some people report having a model citizen in their aquarium, but that is the exception rather than the rule. They may start off as being reef safe, but most will eventually start nipping at your corals, and nearly all of them will pick at your live rock and they are known for turning your inverts into a bit of a snack.
While these fish are considered active, they are also very timid. They do best in aquariums that have plenty of hiding places and bolt holes that they can vanish into when they feel threatened.
They are peaceful fish, and will generally leave their tank mates alone.
Care should be taken when purchasing one of these fish as they are known to be fussy eaters. Make sure your fish is eating prepared foods before adding it to your display tank.

Place your fish in the bucket and then drip acclimate for about 60 minutes at a rate of 3 drips per second. This should bring the fishes water parameters in line with your tanks parameters.
Once your fish has been drip acclimated, catch the fish with a net and place it gently into your tank. Do not put any of the water the fish originally came in, into your tank.
Care should be taken after adding the fish to ensure there is a tightly fitting lid on the aquarium at all times.
