Need help with problem zoas.

[Baker_king12]

Hi sorry if I'm a little slow. My dad bought a saltwater tank and it came with what I think are some sort of Zoa. I'm not 100% as I want told what they where when we got the tank. Recently they have closed up and are looking pale. This is a relatively new tank that hasn't had a ton of time to build up. What should I do if anything to try to save them.

You’ll probably get the best advice with some photos— of the corals, placement relative to the lighting, powerheads, etc.—and some water parameters. Best wishes!
