I won "Lenny" at the last raffle. since then he has had a field day eating my green hair algae, for that i would like to thank him. however i am now getting worried... there is not much GHA left and im not sure what to feed him. I have read that they will eat mysis shrimp but that is what i feed everybody else and he seems to turn his nose up at it. I understand he is mostly a herbivore so i have tried nori on a clip and he wouldn't even swim near it. what else should i try as i am running out of GHA (which is both a good and bad thing)
