    Thank you. It's fixed.

    You can see that it has only one claw and some legs look like broken.

    I used to keep CPO's almost 2 years ago. I did not know much about keeping inverts then and i kept them in my tap water which had a pH of 7.4, gH of 13 and kH of 11. They used to molt regularly without any issues and females used to carry eggs all the time. But i never managed to keep the Baby CPO's alive.

    I feel maybe the high gH made it possible for the CPO's to molt properly. But i cannot be a 100% sure here.
    Regards

    Thank you for the info. I keep them in a tank with tap water (PH 7.6 GH 7, KH 4.5)
    I hope I mine crayfish will breed, all of them except one look good.

    Although, that sick crayfish from the video has molted todayit's still in the same state, it's laying in a tank corner and doesn't have full set of legs/claws.

    Ok, there is a 'happy end'.

    The second crayfish (it was a male) molted again recently and he is almost fine. He has shortage of only one leg.
    Look at the video with it here: CPO male is almost recovered after unsuccessful molt

    So, you someone will found his crayfish almost dead after next molting, it makes sense to separate it from other crays and wait until it recovers

    If you feed your crayfish algae pellets with spirulina algae in them, or put a drop of iodine in the water your crayfish will probably be able to finish its molting.

    Spirulina algae has iodine in it. Crayfish need iodine to finish molting, iodine deficiency often causes problem with molting process.
