Trying to find something to feed my juvenile Koran angelfish. He has seemed to pick off everything he wants out of the tank... wont go after the sponges... I got him from Matt's Coral Connection in FWB. Matt said he would eat my sponges but doesn't seem to go after them. Any ideas what I can feed him, they also said try krill. I already have some to spot feed my plate coral, should I just dose with some garlic and drop it in the water after it thaws?
