Grats!
I am curious - is that the only anemone in your tank?
A little info for you on BTA's:
1) Your anemone is female. E. quadricolor is a gonochoric anemone, which is a fancy way of saying that individuals have specific sex (versus other anemone species that are hermaphroditic).
2) Female E. quadricolors appear to be significantly more abundant in the wild than males, for reasons currently unknown.
3) E. quadricolor is a broadcast spawner, and typically spawns once (or sometimes twice) per year, with synchronous spawning occurring in the austral summer months between January - April. In the wild, it appears that they spawn shortly (1-7 days) after the full moon. They always spawn a few hours after dark.
4) Typically males begin to spawn about one hour prior to the females, which is why I asked if the female was the only anemone in your tank; in many cases female spawning can be triggered by the presence of male sperm in the water.
In the wild, E. quadricolor can reproduce via fission as well as spawning. I am not aware of any study that specifically states that some individuals only reproduce via one method or the other. However some people who post on this site have had experience where one "strain" of BTA will split frequently, while another (in the same system) will not split at all. Bottom line, I'm not sure you can know definitively.
