Has anyone kept honeycombs (Centromochlus perugiae) in a CO2 tank before? I just turned on my CO2 today and they started breathing fast already. Are catfish in general more sensitive to CO2?
Alright, I just noticed that their gills were flapping rapidly. Hopefully it's just acclimation, as the CO2 wasn't really that high. Rummies were fine, they're just really scared.IME honeycomb cats are more sensitive to CO2 than most fish. When i had my 90G up, they were always the first to suffer when there was a CO2 overdose (if you want to even consider it an "overdose"). Just keep an eye on them. I always noticed that they wouldn't eat if the CO2 was too high, so that's how i judged whether to decrease it or not.
