Little slug guy with two black eyes

[agent00cix]

What’s this little slug looking guy with two black eyes on top? Today I noticed a bunch of white dots against my black background. What may they be?

Could be some kind of nudibranch maybe? It's hard to tell because I cannot see the other side...

For the white dots... It just looks like Halloween has come early to your tank!

If in doubt... Throw it out
I like your candy cane

What a way to waste potentially beneficial/cool inhabitants for your tank. I isolate anything Im not sure about until I can ID it, or observe if its harmful to certain things.

Do the white dots move?

Most likely spirorbid worms on the back glass.

Scoop the slug thing out into a separate container and get a better pic of the top for ID before deciding anything.

Finally was able to snap a good pic of this guy

Looks like a Dermatobranchus sp. nudibranch to me - possibly Dermatobranchus fortunatus, but I’m not sure.

The genus is known for eating octocorals (soft corals, gorgonians, etc.) and/including GSP, so that’s likely a remove nudibranch.
