Hi,
Do rainbow fish have a lower tolerance to co2 than other species?
I have recently added a pair of bosemanni rainbows to my high tech tank and have had to move them back to the quarantine tank as they seem unable to cope with the co2 levels.
They were added when the co2 levels were very low after a 70% water change. Within half an hour of the co2 coming on in the morning they were gasping at the surface even though the other fish were fine and the dc was barely green. Turned the co2 off and they recovered after an hour but the dc was blue.
Turned the co2 rate right down and tried again today but shortly after the dc was green they started gasping again so I've moved them out to the other tank
The other fish show no signs of distress.
I'm wondering if this is normal with rainbowfish or if these have a problem such as gill damage.
Would appreciate advice, thanks
