I have a 35gallon tank with two small clownfish, one black and one orange, my orange clown is staying on the surface of my tank and swimming in its side, he will alternate the side facing however he just stays in a few spaces at the top of my tank always on his side? I think this is a swimbladder problem? He also isn’t eating much, my black clown is active and healthy, Any other ideas or suggestions? How can I fix this problem?
