Hole in Duncan coral?

[Shaina Carey]

I got this Duncan coral on Friday and noticed it had a hole in it after placing it on a frag shelf. Can someone tell me if my hermits were eating it or some kind of disease?

Looks like it may be a female gall crab hole to me - if so, there should be a small, likely white/tan crab in the hole.

When I move all the corals to my.10 gallon when I set it up, I will check it. :)
