The back side of one of my rocks has a shallow cave that gets virtually no light but light-moderate flow. Found these critters hanging from the roof like sponge-bats.
I thought they were pineapple sponges but on closer look definitely something else. Thoughts? They are mostly single tubes but some of them split like tree trunks....
