Two confusions

[DDK]

Hello
My lovely family I have a question as usual. I am attaching the picture of my torch coral. I am confused is this splitting or dying .

And what are the element or specific thing you dose to get the best colour of the coral.

Regards
DDK

Its hard to say without seeing the 'tentacles' more retracted?

That looks like a walled hammer coral. Very finiky IMHO. Make sure it has enough flow
