It's a cyphastrea and no it doesn't need to be fed. Try to keep it on a rock you can remove bc once it gets happy, it will overgrow almost anything it touches.
Agree with others, but would just say be careful with light. The distinction between LPS and SPS is at times arbitrary and not worth a debate on whether this is LPS or SPS, but in terms of care it is much more similar to many LPS. Low to moderate light and moderate flow.
