You mean sexual reproduction? I mean, if you are merely cloning/splitting you can't breed for certain features.
Isn't this frontier research? I heard BTA's reproduced in captivity for the first time only in 2005. If you find a method that succeeds you may be able to public in marine biology science journals.
If you are able to breed anemones then you can select for features that make them more hardy in captivity, like with some fish, and that will really make it easier to keep anemones.
