Black August

Lost 3 of my largest Zaires Blues "Kapampa" in the month of August. One after another within the month. There is no sign of any injury or disease. I suspect it's hydrogen sulfide poisoning as I do have quite a thick layer of gravel in the tank and the fronts do like to dig.

Anyway the good news is, the remaining 6 fishes are now having a better time with the lower bioload and more room to swim around.
