Origin: USA? Some say Florida and Georgia. First appearance in the German pet fish trade.
Max body size: 3.12 Inches
Keeping: You can keep 3 + young ones in an aquarium of 23 inches x 11 inches. Bigger tanks allow for a greater number of individuals. A wide range of pH and GH is possible as long as one avoids the extremes. Extremely tolerance to a wide range of water conditions and quality. You can literally breed them in plastic buckets.
Behavior: Like most crayfish, these are omnivorous and will eat your plants. Intra-species aggression is not big, one can even raise most of the young ones in the adults’ tank.
How to tell apart males from females: No males.
Breeding: As usual, except that there is no mating and eggs are diploid from the beginning. They probably do parthogenesis.
Summary: Can multiply extremely quick. Breed early and often, no males needed, huge number of eggs. Little cannibalism. As they do basically cloning they all look exactly alike, with each dot in the exact same place.
