I have an IT that I have been trying to pellet train, using a large variety of brands, on to pellets for 3 weeks now. I tried stuffing the shrimp early on, but he would get the pellets out. At first he would take them and spit them out. Now they are totally ignored. The only things he would eat were FD krill and market prawns. My concern with those 2 foods is the thiasimine depleting the B1 in the fish over time. I have been researching with no success supplementing the B1 by soaking the krill in a liquid form. Will this remedy the problem? I would have thought he would have eaten something by now. Thanks
