In captivity, the answer is "it doesn't matter." Clownfish may take to non-natural partners.
My ocellaris hosted in BTA's for a few years when they were in the same tank. It did take some 6-7 weeks (or more; I don't remember anymore, this is going back some 6 years ago!) for them to go into them.
But to faithfully answer your question, in the wild, the following species are associated with
Entacmaea quadricolor:
Amphriprion akindynos
A. allardi
A. bicinctus
A. chrysopterus
A. clarkii
A. ephippium
A. frenatus
A. mccullochi
A. melanopus
A. omanensis
A. rubrocinctus
A. tricinctus
Premnas biaculeatus

In a pinch, clarkii clowns pretty much host in all of the hosting anemone species.
Maroons and BTA's always make a nice display IMO.
It's too bad that most of the species associated with BTA's tend to be larger, more aggressive clowns. You have to really like clownfish!
