My cleanup crew consists of about 7 mexican turbo snails.....that's it. lol. As far as the establishment, it hasn't been established for long but the rock was taken out of old tanks so there were PLENTY of copepods. The weird thing is that this is the second fish I have lost within the past month. About a month ago I bought a pajama cardinal. He was small and for the first day he hid. The next day he was NOWHERE to be found. I even tore the tank down two days later and NO sign of him. My stocklist is a sailfin tang, a Koran angelfish (trying to sell), chocolate chp star, firefish, clown, bubble tip anemone, pink tip hatian, and rock anemone. Is there something that could be eating fish? My params are right where they should be.
