Things You'll Need

- Aquarium heater
- Aquarium thermometer
- Substrate (playground sand, aquarium gravel or aquarium sand)
- Terra cotta pots, PVC pipe, aquarium decorations
Instructions
Select a large enough aquarium. Different species have different space requirements. For example, a "red lobster" crayfish only requires 20 gallons per crayfish, while the foot-long "white ghost" crayfish requires 50 gallons per crayfish.
Install aquarium filters. Canister or powerbox filters are recommended. Undergravel filters will not function well with a crayfish digging around in the substrate. Also, instal an aquarium heater and maintain tropical (68 to 85 degree Fahrenheit) temperatures.
Add substrate. Crayfish need sand or gravel to burrow in. This makes them feel secure. Several inches is advisable.
Add decorations to the aquarium. Crayfish need places to hide, especially if there are other crayfish in the tank. Even if they are the only thing in a tank, crayfish feel safer if they have places to hide. PVC pipes and broken terra cotta pipes work well for makeshift caves.
