Cambarus affinis

Cambarus affinis is a species of crayfish known for its aggressive nature, especially in confined spaces. It requires ample hiding places such as rocks, wood, and dense vegetation. It is a burrowing species, so a soft substrate is essential for their natural behavior. The species is known for its ability to regenerate lost appendages, but it is still important to maintain a peaceful environment to avoid frequent skirmishes. They can be kept individually or in larger colonies provided each has enough space.
