I just found my other oto dead too. This is rediculous. I had them in the tank for a month before and they were fine? There is still brown algae in the tank that appears on the glass. That should have been enough food, right?
One thing I did notice last night, is that the oto was on my heater cord right by the top of the tank, and it looked like it was breathing heavy. None of the other fish were doing that? He was alive last night, now dead.
I would like to get to the bottem of this. Really. There has to be an explanation, why they both died, one more later.
Please, does anyone have a clue?
