Samhain
Satin, Lace, and Sequins
So I have several small (1 cm or less) white tubes that have started growing out of my uppermost rocks. They appear to have teeny tiny crowns on top of them, but I haven't noticed them withdrawing into the tubes. I don't think they're bad; I just don't know what they are. I have a couple pictures, but the critters are hard to see since they're tiny and on rocks near the back of the tank.
