One has settled on a broken snail shell. This leaves it subject to rolling, being walked on, being buried in the sand, but also increases its exposure to possible foods.
|Anthopleura elegantissima. Still a baby; they grow up to 10 inches across.|
|This one's a bit larger. The base is green, the tentacles tipped with pink, with white markings. And this one has a pretty striped oral disc. With a spiky hermit crab foot on the side.|
|Two pink-tipped anemones and a hairy hermit, on an oyster shell. The one on the right has something in its mouth. In the next photo I took, a few minutes later, only a tip was showing. Anemones swallow slowly.|
Processing that last photo, I noticed a tiny critter near the bottom, too small to be seen clearly.
|Here it is, with a section of hermit antenna for size comparison.|
I don't know what this is. It looks like a snail, but not like any snail that I've seen on the beach or in the tank. It is slightly larger than a copepod, maybe 2 or 3 mm. long. Another hitchhiker, or a tank newborn?
I'll search the tank, and see if I can find in again.
(Update: I took dozens of photos of the area, and found another three of these critters, none as clear as the one above. I think they're baby snails.)
*That makes 8** anemones in the tank. That I know about. 4 pink-tipped, 2 orange-striped greens, one plumose anemone, and one burrowing anemone. There may be more, hiding among the barnacles or the algae.
** 9. 3 orange-striped green anemones.
