I've been told that there is a treatment for scaleless catfish for ich. Does anyone know if this is true and can it be used for syno. multipunctatis and petricola? I had to treat my multipunctatis by having their tank very hot back in December and although it worked the idea of a treatment appeals to me. Now I have increased my syno collection I'm always looking for alternatives in case it happens again.

Thanks in advance, Walrus

So if malachite green is ok for s. eupterus, will it be ok for multipuntatis and petricola? I have schoutendeni as well. Apologies if this sounds like an obvious question but I want to get it right.
