That's a nudibranch. Got any zoas or montis? It's harmful to coral.

yes frag tank is mostly zoas

Looks very much like a zoa eating nudi... kill it with fire you may have more if you have zoas in that tank... check carefully and you may need to dip in malachite green (will kill nudis AND eggs).

I'd start looking closely at all your zoas with a magnifying glass if you have one. There's never just "one" IME

Remove the corals and start dipping them. Put a small power head or keep blowing them off with a baster while dipping. Coral rx pro worked great against nudis, they released quickly. Most likely you'll have eggs so multiple dips over a period of time will be necessary.
