   • Care Level: Generally considered to be moderate. They require a well-maintained aquarium with suitable water parameters.
   • Temperament: Can vary, but many Mexican crayfish are relatively peaceful compared to some other crayfish species. However, they can be territorial, especially during molting.

2. Care Considerations:

   • Tank Size: Provide a tank with at least 10 gallons or more, depending on the number of crayfish and other tank inhabitants.
   • Water Parameters: Usually prefer slightly alkaline to neutral water with temperatures around 70-78°F (21-26°C).
