the sunny contradiction

[crystalz]

I've recently aquired a sun coral. beautiful colour... but. seems it won't open until the lights in my tank are out no matter where i move it. I was just wondering if anyone else who owns or has owned this type of coral has any care tips. I've been told that each polyp must be fed individually. I have a hard time believing that in the wild food just hops into this coral and waits for it to eat it but maybe thats the case. Any tips or knowledge would be great.
