How quickly do BTAs split?

[benjc]

I've got a large BTA that moved on me when I did a 3-day lights-out to battle some dinoflagellates. In the anemone's new location I can clearly see the oral disk and there is a second, smaller mouth near the main mouth. Am I correct to assume this means my BTA is in the process of splitting, and if so, how long should I expect the process to take?

it may take a couple weeks or a couple days my bta has split four times but every time it was different watch for the nem to start changing shape into more of an egg like it is pulling its self apart then you will know it is close.
