The Longnose Filefish is a small filefish. Their small size combined with their beautiful pattern of orangish spots on a greenish-blue body would make you think this is an ideal fish for most tanks.
This fish is unfortunately only for experienced aquarists. The main reason is that in nature they mainly feed on Acropora polyps. Besides the fact that they are very hard (but but not impossible) to convert to other food, the question remains whether they do need Acropora polyps to stay healthy on the long run. This is why we advise to only add these fish to a tank with a lot of fast growing Acropora.
They are generally reef safe, however it is possible that they may nip some coral polyps.
Their diet should include a variety of shaved shrimp, squid, scallop, mysis shrimp, freeze-dried krill soaked in a vitamin supplement, and frozen marine algae. It should be fed no fewer than three times per day.
