Is those corals alright?

[Notsolostfish]

Got those corals few hours ago, dipped them in coral RX. They do seem to open. And good tissue why they are not fully extended because lights off. But what about the bone structure at the top showing is that healthy? Or not?

The skeleton should be completely covered ideally.
Watch it and if it's happy and healthy it will grow over that, if algae grows on it that's usually a bad sign.
