I picked up a light green Gig?? at the LFS today. It looked healthy and was hosting 2 skunk clowns. But in my tank it looks less and less like a gig. The tentacles vibrate quite a bit. Not all at once, but at any given moment some are vibrating. The verrucae are blue/purple which is good. With the pumps on it does hold it's disk folded, but it plopped out flat when I turned the pumps off for a photo. What do you think? Sun anemone or Gigantea?
