Several people asked questions about levamisole, praziquantel and flubenol. I apologize, but right now I do not have the time necessary to give a lot of details. For flubenol and praziquatel, they are however available in the paper on Discus diseases that I wrote, which is still largely valid for Apistos. You can find it also at: http://world.std.com/~enjolras/symtreat.htm For levamisole, I do not have direct experience, but it is consistently reported as very safe and effective for nematode infections by many people on this and other lists. Ken Laidlaw from the UK was, as far as I recall, the first to report its efficacy on this list, providing the following advice: Drug - Levacide (TM) = Levamisole Hydrochloride 7.5% concentration. Note: different concentrations can be used e.g. 1,5% just adjust quantity accordingly. Dose - 1ml in 7.5litres of tank water. First mix required quantity in luke warm water. Then pour into tank. After 24 hours perform 100% water change if possible. Treat all tanks and fish not just those showing signs of infestation. The amount available from farm suppliers (usually 0.5l) is obviously enough to treat 3750l (approx 900 gallons) so it is quite affordable. This amount cost $18UK = $25US. If you have given fish to friends you could also treat there tanks. NOTE: LEVAMISOLE 7.5% = 7.5G / 100 ML TARGET CONCENTRATION IN AQUARIUM WATER: 10 MG/L Flubenol is in theory an excellent drug for nematode infections, but not all strains respond to treatment, and cases of failure are reported. Same thing (unfortunately) for flukes. It may be due to the fact that it should be administered with a chemical that enhances its absorption. This chemical is however very dangerous to handle, and most people do not use it. So the drug may simply be too unsoluble to be affective by itself. For signs and syptoms of the verious diseases, the best thing to do is to buy and carefully read one of the books on fish diseases for hobby use (see bibliography at the end of my little paper).
