Greetings all, bought an amazing looking silver saum with a nuchal hump @ 2 inches, however, found that he had what feces and was reluctant to eat, and when he tried he just spit the pellets out. After some excellent advice, soaking Mysis shrimp in Metro, he has been eating these like mad, and I've noticed his dung was a normal brownish color after 1 day. How long should I continue his treatment? Thx in advance...
