Snail's shells empty and slim covered...?

Never heard of that before Brad! That's disgusting! Yuck, worms can be so gross.

But hey...Key Equine, I noticed your SG is 1.023 which is fine for a fish only tank, but if you plan on keeping a reef tank you should bump that up to 1.026.

I had a huge Polyclad Flatworm that ate snails and actually ate a small Clam in my old tank. The beast was completely nocturnal and only ate snails, I caught it one night dragging a snail into a hole.

I identified the Flatworm as the one that I have linked below;
