Need help with ID Possible bubble tip?

[MichaelGee]

Added a new piece of rock to my tank with a few ricordea mushrooms on it. I put the frag rock in about 2 weeks ago, was cleaning my sand today and about 2 hours later I noticed this on the back of a main rock structure. I started this tank with dry rock so I know this came from the ricordea frag rock I just added. Can anyone help me i.d.? Looks like an unhappy BTA but im honestly not sure. Sorry for the crappy pictures. Tried to get the best shot in an awkward spot. Thanks!

I wish I could get more. It wandered off the rock and parked there, opens up during the day but never really looks to "happy" to me. I may leave it alone and see what happens. If it starts showing signs of death ill remove it. Ill try to snag a better picture when its fully open tomorrow.
