I bought a gorgeous colony of purple zoas. I didn't notice the red "tubes" on the rock until they opened and closed! Nothing comes out in the day or night and they look hollow. But they DO open and close periodically.
What is it??
(Top right of the photo is the colony on the rock.)
Close up macro. (Diameter about the same as a pencil.)
If you know what it is, can you tell me what kind of care it needs? For some reason I think it's non-photosynthetic (like a sun coral).
