hi - clownfish will host anything that they like to host. even if you get a rbta it does not guarantee that they will host it.
i have seen clownfish hosting giant clam.
as for the gonio, if the gonio is healthy it will learn to adapt to the clownfish.
if the gonio is unhealthy or weak then the clownfish will irritate it and it will lose heads slowly.
my clownfishes are hosting hammer coral eventhough i have rbta just next to the hammer coral.
