Duncan coral mouth open/Healthy Coral?

[NicksTanks223]

I just bought my first Duncan frag today and I was wondering if it looked healthy. I’m wondering because from what I can tell from pictures of other Duncan’s their mouth is not supposed to be or is not normally opened this far. I’ve also heard of anemones throwing up their guts if they are unhealthy or unhappy. Thanks ahead of time!

You probably don't need to worry as you just put it in the tank. Mine does this when it poops after feeding. It's just stressed right now.
