British native marine aquarium update December 2012

My tank is ticking over nicely. The two cuttlefish have been entertaining lots of guests over Christmas. However I am concerned about one of them. The eyelids are tightly closed and its movement does not appear to be under full control. There is a slight bulge to the rear of the mantle and it seems to be slightly positively buoyant. Not sure if I will remove to form the tank yet for quarantine but is still seems to be feeding which is encouraging. Apart from  that the cushion stars, sea urchin, anemones, top shells, periwinkles and netted whelk all seem to be doing well. The odd periwinkle falls prey to the cushion stars but that is not a problem. Here are some pictures and videos below.
