Natural Environment: Inhabit clear lagoons and outer reef areas

General Husbandry: Has a temperature range of 75 - 82°F (24 - 28°C) and feeds upon algae covered rock and coral branches/mounds. Even though still quite attractive, they are far too large for most hobbyist aquariums. Requires numerous feedings per day with a varied diet containing some meaty foodstuffs and a lot of vegetable matter. Safe to keep with soft corals but not stony corals. It also sometimes uses its head to dislodge coral pieces to chew on. Rarely seen in the trade.
