I’m looking at my tank at night and see this disgusting looking creature making it’s way across my rocks. Is this a snail out of its shell I didn’t know that was even possible. It’s antennas look longer than ones of my Trochus snails…

Yep. Stomatella. Great little detritivores (also may eat certain types of algae).
They’re herbivores, they will destroy most algae. They’re also interesting to watch as they actually stretch out and stand up to get a better view of things… or to spluge. They spluge a lot.

Where did this thing even come from my tank is 8 months old, I did start with some live rock but this is the first time ever seeing this thing
They usually live under and in your rocks and only come out at night. Occasionally you’ll see them during the day, but they’re pretty elusive. That said, if you see one, you’ve probably got fifty. There are several different types, there’s a jet black one with a white little shell part that’s actually quite pretty.

Stomatella snails are awesome little guys. I have exactly one that came as a hitchhiker. I've never really seen vendors sell them.

Lol I was like what in the world is this thing. Wild how for 8 months I’ve never saw it
I would say you have a lot more surprises coming your way, especially if you spend time watching your tank at night with a flashlight. Snails, worms, urchins, starfish, crabs, shrimp, tunicates, sponges, all come in on that rock.

I agree. I had bought live rock and 6 months later saw a pencil urchin the size of a quarter toppled all of my upper rock work.
So yup. keep an eye out at night. You never know who's out and about playing.
