New to MonsterFish this is my first post not really very experienced in post but I need major help. I have a 55 gal tank, 2 filter, air pump etc. Water is changed regularly and is crystal clear. Test are all normal. Our clown loach which we've had for 3 years stop coming out when it was feeding time, he would hide and then come out after. So I started watching for him to throw him an extra blood worm cubic. About a week after this started I saw him swimming sideways, then upside down until he just fell to the bottom of the tank. I put him in a quar. tank put in Melafix - no help, I have done two rounds of tetracycline -no help. He swimming to the top and still moves around the tank but he can't lay upright or swim upright. And I've tried English Peas too. But since he can't stay upright he can't feed himself, so we've devised a little stick that we can hold blood worms in and hold it down to him so he can eat something. I can tell he wants to eat but just can't get to it. Don't know what else to do. Its been 3 weeks like this. HELP I appreciate any advise.
