You know, my guy looks just like that too. However, all the BTA that I have seen have the short stubby bubble tip like tenticles. My BTA looks just like yours, but the tips are pink and it is a GBTA, not the RBTA. I know ppl can mistag things easy -- they aren't marine biologist, they just work there. I hope someone with some knowledge can chime in b/c I still wonder what my anenome is. Every once in a while I will see one of his tenticles turn into the bubble like shape that gives it the name, but most of the time he looks just like the picture you show there, but the tenticles are a little fatter.
