Matted Filefish or Copperband Butterfly?

[Spyd]

I had great success with my CBB. It ate like crazy! But, the LFS here gets them eating before you purchase them... Novel idea!! I watched it pig out on mysis before I bought it. It took care of the few aiptasia heads that were tucked in with my zoas from my old system. The only problem with the CBB was that it also liked SPS!! It liked to pick the flesh right off of some of my nicest corals. I ended up having to sell it for that reason alone.

I would go with Berghia Nudibranches. Yes, they are a little pricey but they are completely reef safe and only eat aiptasia. They are the safest bet to rid your tank of aiptasia. Once it is all most gone, then sell some off and get our money back. They are a very easy sell!!
