I had a friend give me rock that turned out to have 4 sun coral polyps on it. I have had it for about a year and it is a pain in my butt. I only feed it. Everything else just eats then. The polyps are small and have slim bodies. When I got it they were just orange spots. So I have brought it back some what. How do you feed? Everything robs it when I feed. I have tried holding it to feed bit it won't eat. I have covered it but it seems to not get what I but on it. I don't know what to do. I like it and its difficulty. I would like to feel like it is thriving. When one polyp takes off another one falls behind.
