The sticky thread in this forum shows you exactly what hosts what naturally:

BTA hosts the following:
Amphiprion akindynos - Barrier Reef Clownfish
A. clarkii - Clark's Clownfish
A. frenatus - Tomato Clownfish
A. melanopus - Red and Black Clownfish
Why not look for other types of anemones too? I went with an h. mag so I could get ocellaris to be hosted.
