Can Tangs Host a Toadstool?

[Aspect]

Weird question, I've had a blue tang in my sump until he grew large enough to be put into my DT. He's been in the DT for about a week now and he's been hanging around one of my toadstools like a clownfish hosting an anemone. He will come over to eat where I drop pellets/brine shrimp in, but then goes right back after eating. Anyone else experience this?

Tangs don't live in corals like clowns do with anemones (not coral but still). They can hide amongst corals though.
