The Marcellae Butterfly is another rare species. The strong dorsal spines and golden coloration make this a true show stopper. Some may recognize the shape of this fish, as it is very similar to Prognathodes aya.
To keep at cooler temperatures as the Marcellae Butterfly is a deep water species (16-19 C) and provide plenty of hiding places and an established reef structure, acclimate at lowered lightning, may not acclimate to intense lighting, difficult to keep long term unless adequate temperature can be maintained. In the wild it feed an Bethic invertebrates, tube worms and is known to peck at some soft and hard coral polyps.
Butterflyfish are not recommended for reefs as they will pick at or eat a wide variety of corals, fan worms, and other invertebrates. Most Butterflyfish are known to pick at Aiptaisia, a parasitic anemone.
