Nice. I give a guess as to the species of the anemone.
The anemone is either M. doreensis ir H. crispa. I lead toward H. crispa due to two reasons, neither of wich is 100%
1. Shorter tentacles and seem numerous more likely H. crispa
2. A. percula natural hose is H. crispa, not M. doreensis
Only you can find out 100% certain by looking at the colum of this anemone.
