One of my cories is breathing rapidly, one of his barbels is red, and his mouth seems to be at a weird angle.

I’d do a large water change and watch him. Have you tested your parameters.

 

[DancingBetta]

Yeah. 0 ammonia, nitrites, and nitrates. 7.4 ph. Ok I’ll do a water change. Thanks

 

[FishGuest5123]

Is your tank heavily planted or did you lose your cycle? Why 0 nitrates?

I think I read it wrong
