THIS CRAYFISH IS NOT ALLOWED IN THE FOLLOWING STATES, PLEASE DO NOT ORDER IF YOU LIVE IN ONE OF THESE STATES Wisconsin, United States Missouri, United States Remarks: Electric blue crayfish are a beautiful color morph of the Florida crayfish. Their color is a mutation that naturally occurs in the wild and can be bred for in captivity. This vibrant blue color has made them very popular within the hobby, but they are not suitable for every aquarium. While electric blue crayfish may seem to just be scavengers, they are also opportunistic predators. If a fish or another invertebrate get close enough or the crayfish manages to sneak up on them, it will attack and attempt to eat them. Even larger fish can end up with torn fins from attempted predation. These attacks usually occur at night so while things may seem fine during the day, other tank inhabitants could be getting harassed at night.   Plants should only be included in their tanks if you are okay with them possibly being eaten as the crayfish may see them as food. Furthermore, crayfish must frequently molt their exoskeleton leaving them soft and vulnerable for a short period of time while the new exoskeleton hardens. For this reason, mineral sources such as shells and mineral stones along with plenty of hiding spaces should be provided to protect them from being attacked by fish or other invertebrates and to help form their new shell. Because of their aggressive demeanor and occasional vulnerability, crayfish such as this large species are best kept alone. These crayfish, however, make up for having to have a tank all to themselves in that they are very active, grow to a rather large size, are easy to breed, and display some of the best blue color you will see in the hobby. B-Grade Crayfish are missing a claw or leg(s). These grow back with time! DISCLAIMER: Many states have regulations prohibiting the import of crayfish.
