Watching the anenome split!

This weekend I watched an amazing split unfold. I received this long tenticle anenome a few months back from the Wiemers when they parted out their tank. Well here it is....If you look at the first few pics you can see it's foot attached to seperate rocks. I was wondering why it came out of the sand bed , my first thought it was making a move from the BTA I got from Bruce. If you will notice the progression in the pics there will be a final seperation. There positions at this time one on the right much smaller and after 2 days in a cave moved out to open up on the right of the BTA. The one on the left of the BTA hasen't moved since the split and move on Sunday. My pics are from right to left. Sorry, I need to work on my pic postings.
