A few years ago I had a dark maroon clown fish that hosted in a condylactis. They kept this relationship for over two years until I tore down the tank. Condy's are easier to keep, and cheap.
Sorry about the spelling.
veryfew anemonies will host in a condy. It is not natural for any species but very very rarely you will find some freak that does it. (not saying yoru fish are freaks. lol)
BTAs are most often suggested for a clown host because most clowns will host them, but you have to pair up the clown and anem based on species.
i have a pair of ocillaris clowns which have hosted an open brain, anthillia, a flower pot, macro algae, and currently reside in a bunch of xenia. They have never stepped into my BTA or even my 25 headed frogspawn.
they will literaly host whatever they want. i have seen corners, rocks, even algae clips and powerheads. you dont need an anem.
and to awnser a previous question about if anyone has seen any fake anems that didnt look cheesey: IMHO, i dont think they make any
