I've noticed recently that the two small gorgonian frags added at the end of September 2020 seem to have developed some strange elongated polyp tips which look a lot like sweeper tentacles. As far as I was aware gorgonians didn't produce sweeper tentacles but according to 'The Reef Aquarium, Vol 2' by Sprung and Delbeek some species actually can (Erythropodium caribaeorum and Muriceopsis flavida). So is this what I'm seeing here and if so why is it producing them? There is no obvious encroaching coral so I am currently at a bit of a loss. I'll have to keep watching them carefully to see how it develops.
