Found this thing crawling around my rocks today. Never seen it before. LFS didn't know for sure. One said maybe Stomatella, another guy said maybe a Nudibranch. My Galaxy said sea cucumber lol. Appreciate it!

Definitely a nudibranch and the type that is known to eat zoanthids. If you have zoanthids now or plan to have them in the future, you may want to get rid of this hitchhiker while you have it in sight.

I just got my first coral from Savvy Seahorse and introduced it yesterday (Neon Green Clove Star Polyp) then saw this thing today. Dipped in Coral RX before adding. I netted the thing out and tossed him. Anything else I should do proactively? Attached a video of the new and only coral

Yeah, that's a Dermatobranchus species nudibranch - they eat Octocorals (soft corals, GSP, gorgonians, etc.); so they're not keepers.

Remove any you can find and keep an eye out for egg spirals on the corals (especially your new one).

Do you have a good picture for reference of the egg spirals? I see a little stringyness on top of clove Polyps, one string with a slight brownish hue. But not sure if that's what I'm looking for. Good eye to all of you by the way
