sun coral

[Raul R Badillo]

I got a sun coral from a friend that tore her tank down and it wasn't opening up for her anymore. same in my tank it wont open up. I wanna feed it but how if its now extending its tenticles to feed?

You'll find a sticky post titled 'Care of large polyp non-photosynthetic corals'. It talks about how to entice it to open and how to feed.
