Synanceia horrida

Datasheet

General Description

The Estuarine stonefish, also known by its scientific name Synanceia horrida, belongs to the Synanceiidae family, which is renowned for its highly venomous fish species. These stonefish are considered one of the most poisonous fish globally and are typically found in the Indo-West Pacific region, ranging from India to Australia. They possess a unique ability to camouflage themselves as stones or rocks on the ocean floor, making them challenging to spot.

Aquarium Suitability

Due to their highly venomous nature, Estuarine stonefish are not recommended for home aquariums. They have specific care requirements and behaviors that make them unsuitable for most hobbyist setups. It is crucial to be cautious when handling these fish as their poisonous spines pose a significant risk to humans and other tank inhabitants.

Demands, Care, and Hardiness

Estuarine stonefish are known to be hardy creatures that do not require a large swimming area but thrive when provided with a suitable substrate for digging. They feed primarily on live fish and shrimp, although some individuals may accept frozen food with training. These stonefish should be fed a varied and nutritious diet a couple of times a week to maintain optimal health.

Reef Suitability

While Estuarine stonefish can be considered reef-safe with caution, their predatory nature and venomous spines make them a potential threat to other reef inhabitants. Careful consideration and monitoring are necessary when keeping them in a reef environment to prevent any harm to corals or other marine life.

Aquarium Setup

Setting up an aquarium for Estuarine stonefish requires a special substrate, such as coral gravel or fine sand, that mimics their natural habitat. Providing hiding spots and minimal decorations in the tank will create a suitable environment for these stonefish to thrive. Additionally, maintaining stable water conditions with a pH of 8.1-8.4, temperature between 22.2-25.6°C, and a specific gravity of 1.020-1.025 is crucial for their well-being.

Behaviour

Despite their peaceful nature towards tank mates, Estuarine stonefish are opportunistic feeders that will consume any small fish or shrimp that fit into their mouths. They exhibit a unique hunting behavior of remaining motionless until prey comes within striking distance, utilizing their venomous spines for defense and hunting purposes.

Feeding and Diet

Estuarine stonefish prefer live feed, such as live fish, shrimp, and crustaceans, to fulfill their dietary needs. Suitable live foods include Mollies, Guppies, and Ghost shrimp, which should be fed a couple of times a week to maintain their health and nutrition.

Habitat and Distribution

In their natural habitat, Estuarine stonefish are found in the East and West Indian Oceans, Australia, Japan, Indonesia, and New Zealand. They inhabit shallow coastal waters near reefs or rocky areas where they can blend in with the surroundings and ambush unsuspecting prey.
