For the past two weeks my one goldfish has been gaping at the top of the tank. This is a community tank but it’s just him. He swims around looking for food after feeding, but other than that he is mostly at the top, gaping. I haven’t really seen any signs illness. Any suggestions?

How big is the tank? Does he have any tank mates? Do you know what your exact water parameters are?

It’s a 40 gallon tank. There is a black Moore goldfish, tetras, tiger barbs, and two snails. As of a couple days ago the ph is about 7.5, the nitrite is 0, the nitrate is about 2, and the ammonia is about 0. I am working on raising the nitrate though.
