Snail with no shell?

[jimv]

I found this weird looking shell less snail looking thing in my QT tank? Any idea what this is? Nudibranch, good, bad?

Looks to me like a zoa-eating nudibranch

It's a stomatella snail. I have many of them in one of my tanks, great little hitchickers

Here is a Zoanthid Eating Nudibranch. They don't look similar to me.

Could have fooled me, I get nervous when I see stuff like that.

Stomatella snail. Great addition to any tank: Congrats.

They do not have a shell? It got me worried. I have never seen anything like it before.

They have a shell but it is covered with a thin membrane. That whitish patch you see behind the head is what's left of their shells: The sheathing over the shell gives them the appearance of being shell-less.

The large bump covering nearly have the upper portion of it's body is the internal shell.

I see. I think I have some smaller ones and they have a shell. So they outgrow it as they mature? Interesting. Thanks for the info!

If you touch them their tail will fall off and wiggle while they get away. A lot of critters and fish will eat them.

Have one in my tank, see it almost never but a couple times I caught it up high spreading it's seed into the current. Part of the CUC basically.

I had one cruising around on my skimmer. Then I accidentally killed it when I took the skimmer out for maintenance and didnt see him hiding on it. Snails +vinegar=dead snail.

I hope he had a family.

I had a couple, but my peppermint shrimp took they out.

I have located a second one. Will these proliferate in the tank?

yes, they are broadcast spawners - it will look like wisps of smoke floating through the water
Here's a cool video of it happening.
