BTW, the goby either doesn't like or can't handle the larger meatier foods. He stares at them hungrily, but the tang swoops in and gobbles it up. I've taken to target feeding him as well as the corals. He actually takes rotifers and cyclops thawed in DTs right from the pipette. He must be starving to let me hand feed him! These foods are the only thing the tang doesn't devour. He still eats them. He just doesn't chase down every piece.
