My story is I have a 12" silver that i got for about 2 and a half weeks now. My problem is his previous owner has been feeding him only feeder fishes since he was 3" or so. Now he will only eat fishes and he is still afraid of me. I tried feeding him crickets and krill but he is scared to approach me, even after slowly approaching him everytime. He has not eaten a single krill and only a handful of crickets (I never saw him eat one, I would have to leave before he would come up) So when I feed him, I just leave the feeders with him (Something I don't like to do). Is there any way I gain his trust? How can I get him to eat new types of food, it looks like he's hooked on feeders.
