Had a Kenya Tree growing on a turbo shell. Woke up this morning and it was gone. Just now saw it laying on the sand, but when I went to grab it. It crawled away. It seems that hermit crabs like pre-decorated homes.
That's great. I have a hermit with a green Palythoa on his back. We call him Radar since it looks like a big dish. Long time ago I had a red legged hermit with a small stag on the front of his shell. It looked like antlers. I wish I had a pick of that.
