Last night my weather loach jumped out of the tank and I found him this morning behind the bookshelf that the tank is on. He was not looking good but is alive. He is not really moving around the tank and when he does it is upside down. He appears to be just hanging there. I gave some stress coat to the tank and also removed all the cat hair from hair with my hands. If I put my hand near him he does dart away but is swimming in a weird upside down way. Anyone have any ideas what I should do?
