New Hammer Coral

[Ximat]

I purchased a Hamer Coral on the 19th. Placed it in my tank on the bottom. It's tenticals have not come out yet. Is this normal? The LFS briefly exposed it to air, could that be a problem? I can still see the tenticals in the body, but the don't extend out.

Tank:

75G
6.4WPG PC&VHO
18.5 GP/h flow
anything else you need to know?

anything else you need to know?

The chemistry numbers/water parameters and how the coral was acclimated would help.

My guess other than that is most likely water flow. Generally speaking, most LPS corals like the flow on the lower side. If flow is too high in a given area, the flow can cause the coral severe stress and the flesh to recede away from the skelaton.

Exsposing this species of coral to air is not a concern for short periods. As long as it was handled properly and no pressure placed on the septa piercing the fleshy polyps, it should not be an issue.

Cheers

The only ones that I know you cant expose to air are Sponges. There might be others but this one I know. Have a good day
