Whale Shark

Overview

The largest fish in the world, a gentle filter-feeder with a spotted pattern, harmless to humans. Native to Tropical seas worldwide, it is a popular choice among aquarists for its distinctive appearance and behavior.

History & Origin

Whale Shark originates from Tropical seas worldwide. 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

Whale Shark is a giant fish, generally measuring about 10–18 m when fully grown. Its body shape and species-specific coloration make it easy to recognize among Sharks.

Temperament

Whale 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, Whale Shark typically lives 70–100 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.
