I picked up some Otos yesterday, and they seem to be struggling with CO2. Heavy rapid breathing and not much movement. Is this common or do they just need to adapt? They did eat nearly all diatoms in the tank during the night. (which is very impressive!)
I've got Glowlight tetras and dwarf cliklids doing fine, no heavy breathing or abnormal behaviour.
