Found an empty snail shell. This scares me into thinking I still have a polyclad flatworm. Here's wishing I had started my tank with dead rock....Anymore dead snails and I may have to.
I have reef systems that are decades old and I've never had any longterm success with snails. Got urchins bought in the '90s and had Sally Lightfoots 4-5 but snails rarely make it to a year.
They can, I had a Astraea that lived for 8-10 years and and a shell over 2" tall and the diameter of a $.50 piece. But one out of thousands of shells I've seen isn't a good ratio.
