Datasheet

General Description

The Sargassum Fish, scientifically known as Histrio histrio, belongs to the Antennariidae family. Its body displays a blend of mottled brown and tan colors, resembling an ornate rock rather than a typical fish.

Aquarium Suitability

With a peaceful temperament, this species can make a suitable addition to a reef tank, preferably of at least 30 gallons in size.

Demands, Care, and Hardiness

Categorized as moderately demanding, the Sargassum Fish is relatively hardy as long as water parameters are maintained within specific ranges: a pH of 8.1-8.4, a specific gravity of 1.020-1.025, and a carbonate hardness (dKH) of 8-12.

Reef Suitability

Reef-compatible, the Sargassum Fish enjoys perching on coral ledges within a reef setting, adding a unique touch to the tank's aesthetics.

Aquarium Setup

When setting up an aquarium for the Sargassum Fish, ensure a minimum tank size of 30 gallons, a stable pH level between 8.1-8.4, and a specific gravity ranging from 1.020 to 1.025. Include ample hiding spots and coral ledges for perching.

Behaviour

Known for its peaceful temperament, the Sargassum Fish employs an ambush feeding strategy, patiently waiting for unsuspecting prey to pass by before striking swiftly to capture and consume it whole.

Feeding and Diet

This carnivorous species primarily feeds on feeder fish and shrimp. Care should be taken not to overfeed, as this may lead to a potential loss of appetite in the Sargassum Fish.

Habitat and Distribution

The Sargassum Fish is commonly found in tropical waters, particularly in regions with coral reefs where it can camouflage itself among the rocks and corals.
