No idea what or where this came from?

I dip absolutely everything I put in my tank coral/rock wise. I saw this on the bottom of my tank and thought it was a mass of eggs or spaghetti worms. I pulled it out and set it in cup while I finished doing maintenance. After I finished I took a gander in the cup before I flushed it and I saw this adorable thing. I'm sure it's not good and will somehow kill everything but I put it back. Looks kinda like a Lettuce Sea Slug. Any ideas?

Not a lettuce nudi but definitely a nudibranch. I have read that some nudis that eat zoanthids turn the color of what they eat. Maybe thats the same case and this one just eats algae. Not really sure if hes good or bad though!

Looks like a lettuce nudi to me but might do some research to make sure lol

Actually it may be a lettuce nudi. I guess im just used to seeing them with a lot more ruffles. This one looks pretty similar to yours other than the white spots.
