I added a red devil to my tank about a week ago and he isn't going after the floating pellets that my oscar's eat. He will pick up stuff that falls to the bottom. I was thinking maybe he was given sinking pellets. My question is will he end up eating the floating pellets or do I need to go get some sinking ones? It would be nice for the fish to eat the same food. Not sure if it matters but the rd might be mixed with a little midas.
