Good Utility fish for a 20G Frag Tank?

[Northwest_Scapes_]

Hi! So like the title says, i upgraded my old 10g frag tank to a 20 since I was running out of space which means I've got some room for a couple utility fish for algae/pests/etc. Currently my lineup would probably be a Pink Streaked Wrasse & a Lawn Mower Blenny, would these 2 be good fits? Any other suggestions are welcome!

Maybe a captive breed yellow tang when Biota gets them back in.
They come small, but I don't know how fast they grow.

A Biota Yellow Tang has always been something I've wanted, but yeah I'm not sure how fast they grow either. Plus I probably wouldn't save up in time to afford one without getting sidetracked with other stuff haha
