2 of the infamous White Poopers were found dead on the gravel within a short distance from each other yesterday afternoon. One had a bump along it's back and gill/cheek area was reddish, the other was perfect except for some redness around the middle of the tail. Too small to see anything other than major damage, of which there doesn't seem to be any.
Unfortunately ran out of nitrate test kit but ammonia and Ph were all fine. The only other difference now is that the biggest gourami is now looking particularly unsociable and hanging out at the back of the tank. All I can put it down to is either aggression among the 4 or they ate something that didn't agree with them. For dinner the night before they'd had microworms and some dried brine shrimp, nothing spectacular or out of the ordinary. The other remaining fish is unperturbed and continues to mill around the tank as if nothing happened... maybe he is the guilty one!
