I tried berghia nudis a while ago. i got 12 from a place in the US. they all arrived alive, and i carefully placed them throughout the tank as the webside instructed using a pipette. cost me around 250$ for them. and six months later, there was no change. tried the matted filefish, and 2 months later, no visible aiptasia.

i got rid of the first filefish as i suspected him of nipping some zoas. hopefully this one will behave =P
