Red Sea specimens tend to lose the eyespot (false eye to confuse predators) on the dorsal fin.
The Threadfin Butterflyfish can be quite shy and should be provided multiple hiding places. This species of Butterflyfish is not reef safe. It should be kept in a live rock-only tank, although it will pick at the rock. It can be employed to clear away Aiptasia however they will also eat ornamental crustacea and anemones.
The Threadfin Butterflyfish's diet should consist of meaty items such as fish, crustaceans, mysis shrimp, and frozen marine foods.
