Isn't a majano anemone the same thing as a glass anemone? In that case, haven't you heard about using peppermint shrimp to clear that up? When I had a 25gal I got a peppermint shrimp and it cleared up my 25 or so anemonies in 3 days. Its real cool to watch them attack them too, and they even eat the big ones. Furthermore, you don't have to be stuck with an 8" long fish in your tank that you only bought out of necessity.
