My RNT's seem to not be enjoying my CO2 levels, despite the other fish in there being OK.
You'll have to excuse the 1yr old and cat trying to get involved!

The CO2 does not seem particually high, the drop checker is green and I still have melt issues & limited plant growth. I'm dosing EI.
When I turn the CO2 up marginally the RNT stay low, lose colour, and their mouths open / close quickly.
Any ideas what it could be? My water is pretty hard if that makes any difference, I think somewhere between 12-14 when tested before.
