Hi Folks, I had a nematode outbreak in some Viejitta's afew months ago. I got a bottle of Levamisol, (Tramisol), in the form of sheep dewormers. These pills are huge. What I did was took 5 oblets,, ground them up, mixed them with some tank water, removed the carbon, and dumped them in the tank. The water went milky cloudy, but the fish didn't seem to mind. By the next morning the tank had cleared. I left this dosage in for another day. The next morning the tank was so cloudy I couldn't even see the fish. I then did a 60% water change on the tank and put back in carbon. The fish were totally cured, and havn't had any probs with nematodes since. These fish are still alive and doing great. They have even spawned. worked great Vicky ------------------------------------------------------------------------- This is the apistogramma mailing list, apisto@majordomo.pobox.com.
