I was wondering if anyone could give me advice on what to feed these fish. Mine won't come out of his burrow yet (I have only had him a few days) and I tried to place some brine shrimp by him but he only gets a little before the other fish grab it. Will he eventually come out to eat, is there another method, or something else to try? Also, I do realize that frozen brine shrimp isn't the most nutritious but it was all I could get my hands on until this weekend. That is my reason for asking now what to buy, I don't want to end up with something he won't eat.
