[edit] Alternative names
- Redclaw Crayfish,
[edit] Sexing
- The adult male gets a distinctive red patch on the outside of his claws, this is absent on females. On the rare "blues" from Cherax Park, Au. the red stripe is replaced with a translucent white on the males.
[edit] Tank compatibility
- They are a bottom feeder and will eat anything veg. they come across, as they are opportunistic eaters. It is not advisable to keep this species in the same aquarium as aquatic frogs or snails, as these are easy prey for this species. Ideally they're best kept in single species tanks only.
[edit] Diet
- These Crayfish are omnivorous, and will act as a scavenger in the aquarium, eating any food that comes to rest on the bottom. Supplement their diet with a quality sinkingsinking pellet, flake food and dried algae.
[edit] Feeding regime
- Feed once or twice a day - supplementing when necessary.
[edit] Environment Specifics
- Plenty of cover should be included in the aquarium, including both rocks and plants. After molting the crayfish is venerable to attack and consumption by others.
- If the exuvia (shed exoskeleton) is removed from the tank after shedding, the crayfish will likely die as this shed will be consumed for vital calcium. If your water has enough calcium in it this will not be an issue ever.
[edit] Behaviour
- They do not burrow. The females are territorial when with eggs. A larger aquarium will be needed if housing more than one. Provide at least 80L (21.1 US G.) per Lobster and include plenty of cover including both rocks and plants.
[edit] Identification
- Generally they are blue to a blue, brown and green color. Because of their selective breeding in the hobby, they will not change their original coloration, except in times of stress or when feed or housed incorrectly. Redclaw is not constrained by its tank size. It will grow regardless of space issues. Please allow plenty of space...
