Dionigi, Sorry, my knowledge of bilogical sciences and the proper adjectives eludes me! I do believe I mean nematodes... I did save the info that you are referring to, but I have noticed in some cases, the tablets are crushed, mixed with tank water, and poured into the tank. In other cases, the pasty mixture is mixed with food with the likelyhood that the fish will ingest the medicine. Which might be the best way to administer the dosage? Again, Thankyou for your help! Phil >(snip)< >...noticed a bright red flagelate... Are you sure you are using the term flagellate appropriately? They are single-cell organisms, and I can't imagine how can they stick out of anything. Did you mean nematode instead? If indeed there is a nematode problem, the recommended treatment (levamisole) has been posted multiple times and is available online on some of the apisto sites. Do you have access to this info? _______________________________________________________________ Get Free Email and Do More On The Web.
