What anemone is most likely to host true clowns?

[Nebthet]

I have a bta and a sebae, both really small in my tank and the only one that is hosting is the sebae to my smallest clownfish at night.

If you do choose to get a sebae though, don't get one that is yellow or white with purple tips as they have been dyed and bleached respectively and take a good amount of care to get back to their natural brown color, if they don't die in a few weeks.
