General information

The Estuarine Stonefish, scientifically known as Synanceia horrida, is one of the most venomous fish in the world. It is a master of camouflage, blending seamlessly with its surroundings, which often leads to unintentional encounters with unwary aquarists or swimmers. Its mottled appearance and rough texture allow it to mimic the look of a rock or coral.

Care

Keeping Synanceia horrida in a home aquarium is not recommended due to its highly venomous spines. However, for public aquariums or experienced hobbyists with a specific interest in venomous species, a species-specific tank with plenty of hiding places and a sandy substrate is essential. The tank should be securely covered to prevent escape and to protect the keeper from accidental stings.

Reproduction

Little is known about the reproductive habits of Synanceia horrida in the wild or in captivity. They are presumed to be oviparous, with females laying eggs that are fertilized externally.

Habitat

Synanceia horrida is found in shallow waters, often in estuaries or amongst mangroves, but also on coral reefs. They are distributed across the Indo-Pacific region, from the Red Sea to the coasts of Australia.

Due to their dangerous nature, these fish are typically not kept by hobbyists, but they serve as a reminder of the incredible adaptations and survival strategies found in marine life.
