Rainbow breathing heavy

[kzoofish]

Hello all,

So one of my rainbows is breathing heavy at the top of the tank, and isn't eating. My water parameters are all testing normal and I recently changes the filter cartridge on my HOB filter.

Any ideas as to what's wrong or how to fix it? Please help me save my OG.

Hi, welcome,

How's the fish going? Water specs still good?

Hello kz...

You need to perform a large water change. If you're not removing and replacing at least half the tank water every week or so, your fish aren't going to be as healthy.

99.9 percent of the things that can go wrong with a tank have to do the water. Keep it pure and your fish and plants will be fine.
