i have 4 limas and they were pretty easy to get off feeders. when hungry enough they started going after krill and cut up worms. they are nocturnal so you will have better luck with the lights off. bloodworms might be a good start for you. few fish can resist them. they arent the most aggressive eaters in my experience so its easier if you dont have anything in there that is a vacuum. best off if the food can sit for a bit so they can take their time getting to it.
