Delphinus. How deep is your sandbed ? It looks like your green gigantea is firmly embedded but no matter what I do I can't get mine to attach to the bottom of the tank. It always ends up attached to the side of a rock. Possibly because my sand is only 1 1/2" deep?
Hi Les, I found that with both my gigantea's they always seemed to prefer attaching to rock but close to the rock/sand interface. That particular tank you see my green in, had a sandbed about 1.5" deep, and was actually attached to a rock. In behind the anemone in that picture is a flatish piece of synthetic live rock which was made into a "cave" structure by using aragacrete over an inflated rubber glove as a mould.
The green gigantea is actually now in a BB tank, all I needed to do was move the rock (I had to unbury the rock out of the sand a little, but no part of the anemone's pedal disk was attached to the bottom of the tank).
Incidentally my brown one started off on the bottom, in its tank, near the rock/sand interface (but still attached to rock) and over time migrated the pedal disk to the top of the rock it's against, not moving in the tank per se, but getting large enough that it needed to move up a little in order to be able to open up more during the day.
For some reason both anemones prefer it down near the bottom of the tank, not like a magnifica which is constantly looking for a path "up." They seem to prefer being "down" or just "up enough" to be able to open up.
Hope this info helps!
BTW, incredible carpet. I'm very jealous.

Nothing beats a purplish gigantea, nothing. I'd trade my two gigantea's, plus my magnifica, for a purple one, AND offer up my eyeteeth and my left liver if I thought it would help sweeten the deal.

(Well OK maybe not my eyeteeth. LOL)
Good luck with the wandering green gigantea, sonofgaladriel. Those first few weeks with a new gigantea are always so nerve wracking because you're always waiting for the other shoe to drop (at least that's how I was). Hopefully he's just settling into the new surroundings. Keep us posted.
