I had to move my fish to a smaller temporary tank. The ammonia got up to 1ppm and I did a 60% water change already. But one clown seems totally find while the other keep swimming to the surface kind of goes on its side for a second then swims around and bit and does it again. It's always in the same spot but there is nothing around it, just the middle of the top of the water, and sometimes he goes up and puts his mouth out of the water
Any advice I really don't want to lose him I bought this tank just to save him.
