The Nurse Shark (Ginglymostoma cirratum) is a distinctive and relatively docile shark species native to warm coastal waters. This small variant is suitable only for advanced marine aquarium enthusiasts due to its size and specialised care needs.
Temperament and Compatibility: Nurse Sharks are generally calm and non-aggressive, making them compatible with larger, non-aggressive tank mates. Avoid housing with small or very active fish, as they may become prey or stressed.
Diet: This species is carnivorous, feeding primarily on crustaceans, molluscs, and small fish. In captivity, provide a varied diet including fresh or frozen shrimp, squid, and specialised shark pellets to ensure balanced nutrition.
Tank Requirements: A minimum tank size of 600 gallons (approximately 2270 litres) is recommended to accommodate their potential growth and swimming needs. The aquarium should feature a sandy substrate to mimic their natural environment and provide hiding spots such as caves or overhangs.
Water Parameters and Environment: Maintain stable marine conditions with temperatures between 24-27°C, salinity at 1.023-1.025 specific gravity, and moderate water flow. Regular water changes and excellent filtration are essential to support their health.
Additional Care Notes: Nurse Sharks are nocturnal and may be more active during the evening. They require a secure tank lid to prevent escape and careful monitoring to avoid injury from tank decorations or tank mates.
