Originally products used to coat cattle hides for flies, the term now gets used for mineral supplements given to giraffes.

Ken's right, why risk it.

There's an understatement, sometimes takes a month or so to become obvious. In the end secondary bacterial infection kills your fish (bloat). > As for Piperazine, Look to where the money is. The aquarium trade is miniscule so theyr'e still selling stains as anti-microbials :(. Humans don't get tapeworm or nematodes often so theres not much investment. However pastoral agriculture's got a multi-billion dollar problem. There's where to find the product. <snip> > I thought this had worked but the worms came back after a month or so.

This is also the problem with fenbendazole ('Panacur' and dog/cat wormers) and oxfendazole ('Systamex' -metabolises to fenbendazole giving more lasting availiability). Unless the active is water soluble it seems you're bound to get another attack. I've seen Ivermectin suggested but it's too toxic for my comfort. > The levamisole really did the trick though. > I had no information on adding the powder directly to the water. No money in aquaria :(. About 5ppm levamisole worked for me. With all these treatments assume your fish are going to die anyway, add a little and if it doesn't work, try some more!. Thats why these lists pooling knowledge are great. Levamisole itself isn't soluble so get the hydrochloride if you can. If you can't buy it as the active "Nilverm" is your next best bet. Some of the generic formulations aren't so great. Nilverm comes in a few flavours, with/without mineral supplements, 4% or 20% active etc., get it plain if you can. Some vet in Nigeria even fed the stuff to village children as a tonic once, apparently it worked a treat!. I'm an industrial chemist and once worked for the local manufacturers. They (I hope) can't sue me too easily any more so here's a little disclosure from memory. It also contains: dye(obviously)-nothing to worry about here. Thickeners are Xanthan gum, Methyl Cellulose, and PolyVinylPyrollidone. These should give your fish an excllent slime coat, they're found in several aquarium products for this purpose. The buffer is Citric acid/Sodium Citrate (pH ~4.5) -not enough to affect those apistos. Antioxidants are sodium metabisulfite (dechlorinates the water too!), NaEDTA (should help to get the iron level up a litte for your plants) and ascorbic acid (aka vitamin C, A.Thiel sells this as a tonic for your fish, and its a supplement in most good flake. Clouds the water slightly though). As I recall the rest is water (kills more people than any other chemical :)). In short Nilverm may as well have been formulated especially for aquaria. Fishes for all! Toado. ----------- Reminder: Kindly quote parsimoniously when replying ------------- This is the apistogramma mailing list, apisto@aquaria.net.
