Mystery wrasse in overflow?!?!?!

[tony_3a]

So, what a shitty day this has been, I noticed my mystery wrasses is in my overflow, I have a standard 90g oceanic rr tank, it has a overflow that is 2 feet tall.

I have one idea, to fill the overflow with cheap gravel from petsmart in order to bring the fish up higher where i can see him and can net him. Anyone have better ideas than this?

Thanks
Tony
