Just was wondering if anyone keeps this fish in a high tech tank? I'm wondering how anyone else's handles a tank with pressurized Co2? I find mine breathes quite heavy while the co2 is on. I've tried lowering co2 levels with no difference. I wonder if these guys are just not suited for a high tank tech, being a bigger fish and all.

They inhabit oxygen-poor water in the wild and breathe air. I doubt CO2 is your issue, but it's not impossible.

Does your fish breathe heavily when you turn off CO2 entirely? Turn off your CO2, do a big water change, and observe his behavior for a few hours.
