    hi all, my crayfish molted a week ago and for the first few days after she seemed fine. She ate an egg shell and most of her moult but I’ve noticed that the back shell and her claw parts of the molt haven’t been eaten. So I looked for her (she’s usually hiding during the day) and she usually gets really defensive when I lift her rock but she just kind of let herself be pushed back with a decoration as I went to see if she would react to me. Her shell got darker since she molted and part of her antennae are missing it seems. Also her tail is curled up under her. Is she sick from the eggshell? She is in a 10 gallon by herself. I think she is just a common brown crayfish (my little sister gave her to me because she used to be a class pet ‘project’. Is she sick? Help!

    I have had her for almost a year now and not seen problems like this by the way.

    Do a 75% water change and gravel clean the substrate every day for the next 2 weeks.
    Make sure any new water is free of chlorine/ chloramine before it's added to the tank.

    Feed the crayfish each day with a variety of foods.

    If you put egg shells in the tank, boil them first to kill off anything on them. You should also check to see if the eggs have been disinfected before they are sent to the shops. Some countries spray chicken eggs with a disinfectant and this can poison aquatic organisms. If your country does spray eggs, then don't put the shell in the tank.
