Stomatella Snail or Some Other Big Ugly?

[The_Paradox]

Any given time I see a handful of these in the sump. I assumed they were stomatella snails due to the pseudo shell and long proboscis. What caught me off guard is a few are around 25-30mm. Do Stomatella get that big? Sorry for the craptastic photo but angle was awkward due to how sump is in located under cabinet.

Cool! I've never seen that before but I want some if they are good.

Unless there are holes somewhere on the shell, then Stomatella is a good guess, and, yes, some of the species can get that big:

Yeah, a Stomatella species would be my first thought since it doesn’t look very “hairy” like abalones typically do. Some species - such as Stomatella planulata - do get pretty large, though (to my knowledge) they’re not common in our tanks.

I guess that’s the million dollar question. I was previously pretty sure these were Stomatellas which are good. I have never seen them get bigger than Nassarius snails though so I’m wondering now.

This is a stomatella that's somewhere in my 110g and was a great surprise to find. Did you know their shells are iridescent?

That think is a chonk! I've never seen one in my tank bigger than a jelly bean and I think something ate them all because I haven't seen one in a long time.

Stomatella or Abalone snail, abalone snails look identical with their shell but abalones have 4 holes at the top of its shell running along its top shell.

no idea why i said they have 4 holes only, might be because the one i found in the coral tank where i work had roughly 4 holes, i looked it up and depending on species they can have anywhere from 2-9 holes at the top.

that thing i circled on the stomatella/abalone looks to be a pyramid snail if im not wrong, they are a pest that feed on clams and starfish just so you are aware if you see them get them out, unless you dont have any clams or starfish, but i would still take em out anyways.

I just found one in my tank for the first time a couple days ago. Mine is also big.

New unknown creature… help ID please

So in the middle of the night I saw this guy. I believe he is a mollusk/snail. Size wise he was pretty big. Inch plus in length about 3/8 thick. He had as you can see a clam like half shell that I don’t believe he could fit into if he wanted to. He was foraging on the live rock. He had feelers...
