These little buggers have apparently been hanging out on the bottom of a large chunk of Florida live rock for a few years and I just noticed they weren't nems of some kind when I was cleaning the tank/working on this persistent caleurpa issue. I'm guessing they're some kind of Duncan but I really don't know. Any ideas? I included a daylight and moonlight photo as I thought perhaps the fluorescence of the tentacles might be a clue. Thanks all!
Could be aiptasia. Hard to tell. If it was Florida rock, most likely a stony coral such as phyllangia americana. Does it have a hard skeleton?
That's what I was thinking. The one one on the left looks just like that. I can see the skeleton, I think.
