Another Aiptasia-eating fish
Posted: Sat Oct 10, 2009 12:35 am
I recently came across a lovely little fish known as the bristletailed filefish (Acreichthys tomentosus). They aren't seen terribly often in the hobby, but they are noted by European aquarists to aggressively eat Aiptasia. I actually went out on a limb and purchased one of these little rarities on LiveAquaria to see if they would be reef safe and live up to the hype. After a few weeks, there are very few individuals of Aiptasia left--a few small, isolated ones remain for now. Anyway, this fish doesn't seem to touch any of the corals that I currently have, several of which are usually prime targets, including Goniopora, Cyphastrea, Trachyphyllia, and assorted "SPS" corals. None are worse for wear, nor have I ever observed the fish picking on anything. Granted, I don't have the huge assortment that some may have, so mileage may vary in terms of what will be picked on. It will also vary by individual to another degree, as well. Just letting everyone who doesn't already know about these guys, in case peppermint shrimp don't work and butterflies are not a good option for you. Another plus about these fish is that not only do they eat Aiptasia and are reasonably reef safe, but they stay small at ~3" and are extremely peaceful.
