The Aiptasia Eating Filefish, Acreichthys tomentosus, is a thin bodied fish colored in shades of green and brown. Their uniquely shaped bodies are dotted with white and dark splotches resembling some types of rock. These fish have lots of personality and do well in a large fish-only aquarium. They like to have rockwork or gorgonians that they can hide behind when startled, and will peer out with a curious eye. The Aiptasia Eating Filefish is also known as the Matted Filefish, Bristletail Filefish, or Matted Leatherjacket. As their name suggests, the Aiptasia Eating Filefish is one of the best reef dwellers for eating pesky aiptasia and glass anemones making them a beneficial and working member of your tank. They are not specialized eaters and will consume most prepared foods as well. They can be shy, aggressive towards small fish except its own species, and should be kept well fed to avoid nipping on corals. 

I cant recommend this fish enough. its peaceful and very useful for getting rid of aiptasia! I had 3 large areas of aiptasia that no amount of zapping worked. This fish got rid of all of them! But then he started eyeing my anemones and I had to return him to a different tank that was free of anemones and corals.

Awesome fish, very healthy, very fun to watch. Like a chameleon that hovers everywhere. I watched it, yes watched it eat a majano first day. It isn't a voracious hunter of them by any means. I have two of them and helping them by supplemental injections of pickling lime and RO TO fight the majano infestation. 2 thumbs up to saltwaterfish.com!

Cute little fish arrived in excellent condition. After acclimating for 2 hours, he was placed into the tank. He was very curious surveying the new tank. Ate some mysis shrimp. He didn't hide and preferred to stay at the front glass. I hope he will eat the tiny aiptasia.
