Electric Blue Crayfish, also known as Procambarus alleni, is a species of crayfish that is native to the State of Florida, as such, they are not restricted in Florida.
Crayfish are excellent escape artists! If your water level is near the top of the tank, if you have rocks and decor large enough for them to reach the surface, or if you have equipment such as airline tubing or heater cords that extend over the side of the tank, they will climb out. To reduce the likelihood of escape, equipment should be suspended overhead so that it does not touch the sides of the tank. If housed in an aquarium, a lid may be required.
