Anyone keeping clams should be aware of pyramid snails These little buggers can really stress out your clams and you if you are not careful. I was unlucky enough to get the snails from a fellow reefer. I never knew how many were on my Gigas until I pulled him out for routine service. Sorry the pictures are some what out of focus, I needed to hurry and didn't have time to set up my tri. This clam weight about 10 lbs without the snails for size comparison.
