Hitchhikers in refuge

[jkentfite]

Sorry for the gross glass. Middle shot, there are two adjacent little critters. There’s dozens in the fuge. They move relatively quickly and are pretty active... are they flatworms? Limpets? Nudibranchs?

The 2 big guys look like pineapple sponge. But theres 2 flat worms to the left of those.
