    I have had this lobster/crayfish since about June of 2016. He was first in a 10 gallon (he was in it while it was cycling... I was not aware of fish science back then). A couple weeks ago I moved him to a very recently cycled 60 gallon. In between my want to move him out of his old tank and today he has had a very strange experience with his exoskeleton. First he started turning this reddish color, and then he molted for the first time in the near half a year I had him. After this he lost his front legs and his shell/body continued to redden. Just 2-3 weeks later he molted again! He grew back his legs and his shell was white. The thing is this time around he very quickly started turning black/gray in color. Little black/gray spots started showing up on his back, claws, and tail. He seems to be behaving normally, but the weird black spots are increasing. Has anyone dealt with something similar? I know some things I can do/try but some extra tips would be greatly appreciated!

    Apparently the freshwater invert forum is super inactive though, whoops.

    In the pictures he is in a plastic container since I had to move him to a different tank.

    Are these spots flat on the surface or are they concave? If so concave it's she'll rot, bacteria is eating away at the chitin, a molt will fix this disease and make sure your water conditions are perfect to ensure healthy development of the lobster also make sure it has a good diet and that the water is hard, as nesscacary metals in the water will help the crayfish to build its exoskeleton

    Thank you so much! Upon further inspection there are definitely some signs of decay where the black spots are. I'll make sure to pay more attention to the condition of the tank and what he is eating from now on.
