I would stop treating him. The gut flora nees to become reestablished. I've noticed the problem with GT's is mostly diet related and less parasitic than most people think. When I would feed Krill as and example I always noticed a day or two of stringy poop. I would also stay away from black worms. GTs need a high amount of vegitable matter in their diet, peas are great along with Hakari Bio-Gold, Omega One Veggie pellets, NLS Thera A and sprulina loaded brine shrimp when thay are younger. these are all foods I've used with success. The trouble with animal proteen is it takes longer to digest and tends to cause elavated levels of bacteria to build up in the digestive tract. GTs digestive system needs to keep moving anything that slows the digestive process causes constipation and then the trouble starts. I treat them more like Mbuna and have very few problems. But like I said since I stoped feeding the occasional krill or worm and keep them on the diet I mentioned above I've had no issues. GL
