Can crayfish live in cold water?

A temperature range of 65-77 F (18-25 C) is best for good growth of most species from the continental United States, but they can survive over a much wider range. Some species are tropical, some require cold water. They are normally 100% aquatic, but they can survive out of the water as long as their gills remain wet.

Crayfish need a tank with fresh water that’s kept clean and free of pollution. A filter is a must and so is a heater if you live in a cold climate — the water should be between 70 and 75 degrees. Check the pH level of the water regularly to ensure it stays around 7.0.

Males tend generally to be larger in size than females, with larger chelae and narrower abdomens. Crawfish tails host small appendages, including swimmerets. Male crawfish carry an extra set of these swimmerets, which are enlarged and hardened. Females possess a small hole just behind their swimmerets.
