Thanks for the replies, guys. I feed mine one starfish about every 2-3 weeks depending on the size of the star. It bothered me at first to give them stars but my urge to own a pair won out. Most of the time I feed them "feeder" linkia but sometimes when they are not available I buy a chocolate chip. I'm still checking into finding some asterinia stars. I've not found any specific site on Harley's. I would just do a search and see what you can find. They are doing very well in my reef and nobody bothers them. I do think you might see more of them in a smaller species tank, but they look so "at home" in the reef I'm going to leave them there. MtnDewMan on Reef Central has a pair in his reef and they have spawned! Who knows, maybe mine will too......
