I moved the four killies to a bare 2.5 gallon. I added one quarter of the small bolus tab, which I ground up with a mortar and pestle, dissolved water, and added to the tank this morning. One of the Camallanus cotti worms dropped out; it was about a 10 mm long, and I could see the pink fluid going up and down the length of the worm, with the naked eye, just like in Tom Waltzek?s video. I?m added another ¼ tablet to the water, since the killies seem fine. I could still see a worm sticking out of the one female, but there wasn?t as many, and it wasn?t out as far as I had seen them before. I also have added one antibiotic Triple Sulfa capsule. I think the Levamisole is working. Susan _______________________________________________ GSAS-Member mailing list GSAS-Member@thekrib.com http://lists.thekrib.com/mailman/listinfo/gsas-member
