In the past week I have lost 75% of my fish and I'm quite depressed, some were with me for the past 4 years. I have tested and retested all the usual levels using both digital and salifert measuring devices - all are within acceptable ranges.
The only thing that has changed in my tank has been the addition of several anemones over the past few months (it's now an anemone-only setup). I found most of them lying on the bottom of the tank breathing heavily, one in particular had deep red marks around the rear tail (almost like bruises).
I walking past the tank yesterday when my pygmy angel suddenly shot out from the rockwork and started swimming frantically across the glass for several minutes. Within 4 hours it was dead.
I am truly puzzled as to what is killing them off. They always seemed to maneuver fine around the anemones, and I assumed if they did happen to touch one it wouldn't be THAT fatal.
I figured it was a good opportunity to shop for some new fish, but I guess if it were the anemones causing the problem then the only suitable ones would be clowns...
