I put this ? on the sick fish forum yesterday. No one answered me and only 8 peaple looked at the question. So I thought i would try it here. I have Harlequin tusk that has been lying at the bottom of my aquarium for 2 days now. Sometimes he will lay on his side for a couple hours then perch him self back up. He looks extremly bloated. (big belly) Does any one have any thought or suggestions. Thanks.
