IME, The Copperband or even better the Chelmon Marginalis (Australian Copperband) are the best candidates for keeping a tank free of unwanted anemones, Majano and Aptasia. YES they have a very poor survival record and it took me 3 of them before getting one to last more than 3 months.. What I have found IME is that the ones smaller than 3" don't survive well as neither do the ones over 5". It seems the medium sized ones fare the best. The C. Marginalis has a better track record but is also 3x the price of a standard Copperband, going for around $150.00. The Long Nose is OK but IT WILL eventually start picking polyps off your SPS, Clams are at high risk, and worms will be non existent. Raccoon will definitely make very short work of any anemones, however if you have corals in that tank, it WILL decimate them very quickly. I have never tried the Bergia, but have had friends tell me they work great unless you have wrasse's in your tank, if so then they will eat them fairly quickly. Peppermint Shrimp have also worked very well for me in the past. I put three of them in my 75G sump that was loaded with Aptasia and within 30 days they were gone. My only problem I have now is that my Banggai Cards are huge now (close to 4.5" from top of dorsal fin to bottom of ventral fins) and the pair of them have taken a strong liking to peppermints. I put 6 of them in my 180 and within 3 days they were history, nice 40.00 snack for the Banggai's :mad2: . I personally will stick with the Chelmon rostratus or Chelmon Marginalis to control my anemone pests.
