Jay, I thought it may be an ammonia / nitrite and or nitrate problem you may have. I take it No2 is Nitrite and No3 is Nitrate readings, this being the case and they read zero it can't be that. Your pH is okay...just, but would be better a good bit more acidic for the Cr. regani but that will likely drop in time. The temperature is also okay. Can anyone else shed any light on the breathing problems with the female Regani???? Helen > I just set the tank up a few days ago. I have a Fluval 304.
