A while ago I noticed that two polyps on my Xenia look a bit strange and have long knobbly stalks with conjoined-twin-like heads. The heads look like they have 15 tentacles with one long one in the centre and both sides pulsing at different times. The polyps are on separate corals though they probably came from the same original. Just thought it was interesting that the mutation happened twice whilst all other polyps look normal with 8 tentacles.
