I have zoa eating amphipods, they have so far eaten a small frag of rastas and are now working on the second rasta frag and a frag of green bay packers. All these frags were full, open, and healthy last week. Now the two left are very irritated and won't open at all right now. They seem to gang up on one closed head at night and then pick at it until they can get to the inside of the zoa. I have been checking each night and will sit and watch them do this, they do not run and hide when I shine the light on them. They are also very large adult amphipods. I have had these frags for quite a long time and haven't added any new amphipods in ove a year. Any ideas as to why these adults have started doing this? Has anyone found a way to stop these amphipods from doing this?
