Few questions on my new carpet

[headstrong]

Need a bit of help ID'ing this anemone. Haddoni or Gig?

It was in a plastic basket when I bought it so I just placed it in the tank in its basket after acclimation. Last night I was able to get it out of the basket and put it on the sand. Over night it's now moved itself into a cave with about 1/4 of it exposed. From what I've read Haddoni's don't like rock, so I'm assuming it's a Gig?
If it's a Gig should I be concerned with it under the rock and not getting much light?

I have two maroons that already share a bubble tip. Any chance they may some day also host in the carpet?

This is a pic after I first put it in the tank.

It looks like a Gigantea to me. It will move to light once it settle in. Does the column have spots on it and bluish or greenish near the foot? Gigantea need much more current than Haddoni

The underside is pink, and there are darker pink (almost red) lines/spots. Don't remember seeing any blue/green spots underneath.

They like to attach to the side or under a rock at or near sand/rock are. They often attach in a cave or crevice and poking out (but not as much as BTA). High random current is best and high light.
Your anemone looks like it is doing well. Good luck with him.

Well got home today and it's now slowly making it's way up the rock structure.
I also noticed the markings on the underside are actually white spots/lines on a pink foot not red or darker pink spots. I have a horrible memory I guess.
