Cheebs, I currently have 3 RBTA's in my anmemone tank, and they look nothing like this anemone. That is what is confising me. As with most RBTA's in capitivity, the 3 RBTA's have the long tentacles, and I rarely see the "bubble" tips. This anemone has much thicker tentacles, with much more spacing between the tentacles. Maybe it's an RBTA on AGH (anemone growth hormone)???
