Last thing I would like to add: on ANY treatment for clowns, I am a recent believer/follower in high protein diets - had a clown, would just NOT respond to ANY treatment for skinny disease - (minus the Levamisole Hydrochloride that I just couldnt get my fins on in the U.S.) - started him on a high protein diet, within 1.5 weeks he stopped loosing weight, 2.5 weeks later he was starting to slowly gain weight back - about 3.5 weeks later, he has noticeably gained weight - In the future, I think any treatment for a clown loach will include a high protein diet - seems to do them VERY good (IMO)
