Yellow slug??

[nlutfi]

Found this guy crawling around on my rock tonight when the lights were off. I pulled it out and put it in a container for the night unsure what it is and if it's safe or not. Looks like a slug about the size of pinky nail, mostly yellow in color.

Looks like a Nudibranch. Some are good, some are bad. Hopefully someone here can identify it for you. @reefsquared

Looks like elysia...eats algae.

Awesome maybe I'll throw him back in then!

Having a hard time finding any pics that match what it looks like online when searching for Elysia. Not doubting you guys just want to make sure before putting it back in the tank.

I did not thank you! It definitely looks like some kind of Elysia, I'm assuming they are all reef safe? Hard to pin point exactly which one it is.
