Hippo tang cleaning sailfin

[FishOkay]

Weird thing I seen today, just wondered if anyone else has seen it before. My hippo was acting like a cleaner wrasse and kind of cleaning my sailfin tang. The sailfin was actually presenting itself like if it were a cleaner wrasse lol. Is that weird? I've never seen it.
