Greg, I, too, try to avoid medicines when possible. For external parasites I use a combination of 1 drop/2 L of malachite green + 1 drop/2 L of 37% Formalin (standard medicinal formaldehyde) in a bare tank. Change 25% of the water after 2 days & repeat the medication practice for a week (3 doses). Apistos can handle this quite well, but some fish with no scales (catfishes) or tiny scales (loaches & characoids) are very sensitive to malachite green. Also increase air in the hospital tank because Formalin absorbs O2 in the water. Try to keep the tank very clean because the Formalin is quickly neutralized by organic matter in the tank. Also try to avoid getting any Formalin on your skin - especially the dry white powder that usually appears around the lid. Formalin is considered a cancer causing substance. Prolonged contact has caused cancer in the internal organisms of test animals. Malachite green also is a suspected carcinogen, so be careful handling these chemicals. Better to be safe than sorry. There are commercially available antiparasite medicines out there that work well, too. Most are organophosphates that are similar to or the same as well known insecticides. I have read that oils & compounds in garlic will kill or drive out parasites in the intestine. The garlic must be crushed & mixed with food. It will not work unless the fish eats it. It is useless for external parasites. I hope this helps. Mike Wise Grzegorz Prusinowski wrote: > > Your female viejita may have gill parasites.
