It's not going to take any sort of food from you. You either have its food on your rocks or you don't. For 2 years I didn't, but now for the past year it seems I do. And yet even now I look at my linkia with a sense of dread (and wonder at its beautiful color), still worrying that I'll see signs of it starting to melt. I truly hope yours does well - I still think they are one of the coolest animals possible for a reef tank.
