Why We Like It:

One of the few fish reliably known to consume pest Aiptasia anemones, this filefish is a useful biological control for problem tanks. Cryptic in appearance but full of personality, it adapts well to prepared foods once established. While often reef compatible, individuals can sometimes sample corals, so observation is important. A practical and interesting addition when dealing with Aiptasia outbreaks.
