I have a limited number of baby Marmorkrebs crayfish to sell. These are the self-cloning crays that reproduce without a male. All the crayfish are females. The crays are about 1/4 inch to 1/2 inch long right now. The price of the crays is $8 each with shipping set at $12 for up to four crays and is $17 for over four crays. Here is an older picture of mom. She looks the same except larger now. These crays have the potential to be very harmful for the environment so caution and responsibility as a steward of our hobby is needed as an owner of these crayfish. A really good use for these crays is to use the babies that are produced as a live food source for your fish.
