Woke up yesterday and strangely the fish were not waiting for food and even did not come to nibble on masstick which is an iresistable food IME. Then i found two dead Swallowtail angels. They looked intact nothing on them. Next day it was the coral beauty. And now my mandrin and fairy wrasse are breathing heavily. The rest of the fish look ok only they are not eating so they are not. These are blue face trigger, copperband, cardinals and clowns. Melanorus and cleaner wrasse are fine and eating for now. Although i have no idea it seem like a bacterial infection.However, as its a reef tank i guess all i can do is wait and see who will survive it. This infestation came of course with a new femail melanorus i tried to introduce to my mature male...also a mistake as he had a change of mind in an hour from courting her to deciding to kill her. She is in the sump perfectly healthy in amphipode heaven.
