Nurse Shark

Overview

A slow bottom-dwelling shark with a broad rounded head, resting in groups on reefs, generally docile. Native to Atlantic & Eastern Pacific, it is a popular choice among aquarists for its distinctive appearance and behavior.

History & Origin

Nurse Shark originates from Atlantic & Eastern Pacific. It has been kept and selectively bred in the aquarium hobby for generations, producing many color forms and regional variants developed through captive breeding.

Appearance & Size

Nurse Shark is a large fish, generally measuring about 2–3.5 m when fully grown. Its body shape and species-specific coloration make it easy to recognize among Sharks.

Temperament

Nurse Shark is generally territorial and can be aggressive toward smaller or similar-shaped tankmates; keep it with robust, size-compatible species and provide ample space and visual barriers.

Care & Husbandry

A marine species best suited to experienced saltwater aquarists, it requires a mature, well-established aquarium with stable salinity (around 1.023–1.025 specific gravity), strong filtration and pristine water quality. Given its size, provide a spacious tank with robust filtration and room to swim. Feed a varied diet of high-quality prepared foods supplemented with live or frozen items, and quarantine new arrivals before adding them to the display.

Health & Lifespan

With good water quality and a balanced diet, Nurse Shark typically lives 25–30 years in captivity. Watch for common aquarium ailments such as parasites, fungal infections and stress-related disease, and maintain stable parameters to keep it thriving.

Popularity & Recognition

Aquarium sharks such as bamboo and epaulette sharks bring a touch of the ocean's apex predator to very large, specialized marine systems.
