So lately things have been going wrong in my tank. To begin with, my Mono died, which was like, okay. Not suspicious at all. Then a little while later I walked passed my tank and my Silver Scat starts freaking out, stops, then dies. Then the rest of my fish were fine. And maybe for the past two weeks my Archer has been weird. On the first night my boyfriend and I walked into my room and he was "dead", but not really. We put him in the three way breeder, and over a minute or two, it was fine. But then progressively, every time we walked past or turned on the light, it would flip out, and "die". It was weird because he wouldn't breath or move or anything, then it would just start living again. He was flipped over and everything. But then, yesterday he died. I don't know what's wrong with everything. Help? The P.H. and Ammonia are fine and everything. I just don't understand what's wrong. This has never happened before. Eep!
