Very small, unfriendly looking snail on acro

[dtruitt]

Found this guy on an acro that's been struggling even after correcting a number of issues. Hes about 2mm long.

I took no prisoners, he is drying out on the kitchen counter now.

My first thought is pyramidellid snail... but I think pyramidellids are much lighter(almost white) in color and have a 'pointier' shell similar to a cerith or trumpet. This shell is different.

Part of me also feels like it looks like a baby assassin snail? But it doesn't have the bright stripes. Hmmm!!

Fingers and toes crossed that we can get a snail expert in here.
