Keeping Redclaw crayfish (Cherax quadricarinatus) involves providing a suitable freshwater environment with hiding spots, maintaining good water quality (pH 7-8.5, moderate hardness), offering an omnivorous diet (sinking pellets, veggies, protein), ensuring escape-proof housing with a secure lid, and managing temperatures between 23-28°C (73-82°F) for optimal growth, while being aware of their potential aggression, especially as juveniles, and strict regulations against releasing them in non-native areas.
