Ok, here's a mystery. These........things are on the live rock in my 72g. There are only 2 of them. There have only been 2 of them. They are not any kind of nem, they are neither slimy nor snotty nor sticky. They feel like shoe leather when touched. They do retreat into a "nub". I have never seen any tentacles come from them, and the color in these photos is true to life. Marc, these are the weird things I was telling you about.

They don't seem to be bothering anything. This tank does support some interesting filter feeders........monkey sea squirts and tunicates, without any supplemental feeding. So, maybe some kind of weird filter feeder? Ideas? Anyone?
