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.

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

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.
