i have heard they are not. Aparently ick needs scales to attach on to. and since eels dont realy have scales, that takes care of that. Also, eels have a thick layer of mucus and slime on them, much thicker and slicker than that of a fish. So the parasite is not able to attach once again. This is what i have heard, i had ickin my tank and my snowflake didnt get it. But if they are under a lot of stress...like a realy lot... then their slime coat will depleat, jsut like a fish, so it may be possible then.
any other experiences?
