Most of mine are about 4" diameter. They can get bigger. They can move, but I've found that once settled they seldom do. When they move they creep, not truck around like a bubble tip. I don't have clowns but I've heard they don't host clowns. They are pretty sticky and I guessing hovering type fish will get eaten. I have a couple of dwarf angels in with mine and so far no problems.
They will host sexy shrimp.. Which is pretty cool!
