"Skinny" loach problem

i think you should move him into QT for a week or so til he fattens up. my 2 clowns out competed my other one for food and it died =(

U could try put in zucchini, cucumber or melon.. gives them all a chance to eat. what are u feeding them?

I have the exact same problem. Although I had the smaller one in a tank by himself and decided to move him in with the others. He's much happier now, has gained some weight but not allot. He has grown since I got him but just not at the rate as the others. He eats all the time, I tend to overfeed...so I do more water changes. I also feed veg's, live food, pellets etc. every week. I did look up on the computer a picture of a loach with skinny disease and mine doesn't look that bad. Do you actually see him eating? I've taken the wait and see approach for now, not saying that's what you should do but as long as he's active and you're sure he's eating could he just be a runt. I have a molly that's a year old and has never grown more than an inch in size. He's not sick, very active and eats great. I'm hoping the same is true for my little clown loach.

It looks like "chronic wasting disease" to me, skinny behind the head. If you can get levamisole, sold in feed stores, it's pretty safe & easy to use. It's getting hard to find though. Flubendazole works too or if they're eating well fenbendazole IN FOOD works too.

Here's Shari's article at loaches.comhttp://www.loaches.com/Members/shari2/levamisole-hydrochloride-1

This guy sells all (he's a vet I think) http://www.inkmkr.com/Fish/ItemsForSale.html

The general idea is to treat it then retreat in ~3 weeks. You may need to use an antibiotic like kanamycin (I think) if you don't see improvement.

I treat all new loaches with levamisole just in case but eventually lost 1 that never seemed as healthy. IMO your fish need medical intervention not just more or better foods. I wouldn't wait.
