Coral not opening

[newbreefr]

Just got a leather coral this Saturday. Not too sure what it is but I’m guessing a toadstool?? Hasn’t opened since I put in tank except for at night. I have a mushroom and zoa that are doing good so not sure what’s going on here.

Normal for Sacrophyton to stay closed while acclimating, and to close routinely. Provide the coral with adequate flow to assist in shedding of waxy coating on crown.

Looks like a toadstool. Mine change often to closed for seemingly no reason.... But when first introduced took about a week to open.
