I am no expert by any means but these questions are fairly simple.
There are GBTAs, RBTA and your noramal BTA I guess. This is usually how distinguished color morph wise.
Yes I have seen some up to 15 inches and even bigger. I know stevewest has a huge RBTA. Not sure how big though.
There are some BTAs that split rapidly once well established and are doing great in their system. These BTAs most likely came from their mother anemone that was in a tank and not in the wild.
This is not really known. Just one of those mysteries. There are plenty of theories and principles but none have been yet proven as a fact. Some theorize that when hungry their tentacles become elongagated and after gettting a meal they shrink and go back to bubble tips. But I have seen BTAs grab a meal and still maintain their long tentacles.
Hope all that helps. Maybe others can elaborate on what I said.
