Invasive snail?

[Gore15]

I had this fellow in the live rock and lost track of it for a while. And I found it last night during nightly inspection. I thought to post here and ask if this is the invasive type of snail?

 

ps: space between the two lines is about 1cm. If you think scale and size matters.

That's a stomatella snail. A good guy. Keep him. 🙂

Yeah, he's a keeper! I found one in my tank that looks identical except it's black a few months ago. I don't see him much because his smaller size makes him real good at fitting into the nooks and crannies that other inverts can't reach. Plus they don't bother anything and they make a fun bragging right/ story to tell when they do come out for other people to see. At least in my opinion since you can't find them in stores and most reefers want one.

Thank you. I put him back into the tank and it happily went after its duties.
