I've got a translucent bivalve in my sump. It closed like a bivalve when I went near it. So this guys been "walking" around or swimming. I jave no sand in my sump. Recently I moved rocks and some junk corals into my Reefer sump out of my 20 gallon. This particular rock had only brown star polyps growing on it. Now it has this translucent bivalve chillin. I can see the darker body through the shell. It's about the size of a quarter.
@Lionfish Lair what do you think of this?
I'll transfer the rock into a Tupperware and bring it into stronger light but for now here it is.
