BEWARE THE FAKES! Some stores (and some individuals) are selling other species “as” Marbled Crayfish. These are usually local-caught, or from Asia, and they may resemble the Marbled Crayfish – but will end up eating the other animals in your aquarium – and they are NOT clones, and will NOT have babies by themselves. BEWARE of low-price crayfish which claim to be Marbled Crayfish – MANY other species do resemble Marbled Crayfish, but are something else.
Concerning “BLUE” Marbled Crayfish – please read the EXPERIMENTS section here.
