I have a Kel and a Mono/Ocell, both around 5". I want to try and start getting them off feeders. I put in freeze dried krill yesterday, and the Mono went after it. I fed it again today. He still not too sure about it, because he spits the pieces out alot, but I believe he has eaten a few too. The Kel shows absolutely no interest. How long generally until the Kel will catch on that this is food? I would think pretty quick, since he sits there and watches the Mono go after it.
