Sargocentron vexillarium

Datasheet

General Description

The Dusky squirrelfish (Sargocentron vexillarium) belongs to the Holocentridae family and is native to the Western Atlantic, from Bermuda and Florida, USA, down to northern South America. With a maximum size of 18.0cm, these fish are known for their red/grey coloring and secretive nature, often hiding amongst stony corals and requiring overhangs and caves in their environment.

Aquarium Suitability

Considered suitable for aquariums, the Dusky squirrelfish is best kept in a tank of at least 600 liters due to its potential aggression if not provided with enough space. They are nocturnal creatures and prefer dimmed lighting, making them most active during darker periods.

Demands, Care, and Hardiness

Categorized as hardy, these fish thrive in water conditions with a pH of 8.1-8.4, a specific gravity of 1.020-1.025, a temperature range of 22.2-25.6°C, and a carbonate hardness of 8-12. Dusky squirrelfish are cautious reef inhabitants and should be introduced carefully due to their territorial behavior.

Reef Suitability

Reef safe with caution, these fish may hide within coral branches such as Acropora coral. They will also seek out other hiding spots in a reef setting, contributing to their secretive nature within the aquarium.

Aquarium Setup

To accommodate the Dusky squirrelfish, provide a tank with ample hiding places like overhangs and caves. Live food may be necessary initially to entice them to eat, particularly if they do not emerge during the day. It is advised to avoid capturing them with a net due to the risk of injuring their large eyes.

Behaviour

Mentioned as potentially aggressive and known to engage in intra-species conflicts, Dusky squirrelfish are more active during nighttime hours. They may exhibit territorial tendencies if not given sufficient space in the aquarium.

Feeding and Diet

The recommended diet for the Dusky squirrelfish includes larger crustaceans, other invertebrates, small crustaceans, and zooplankton. These fish can be easily enticed with a varied diet, especially if offered during their active feeding times.

Dimorphism and Captive Reproduction

Dimorphism details were not provided, and captive reproduction information is not covered for the Dusky squirrelfish.

Habitat and Distribution

Found in the Mexican Gulf and throughout the West Atlantic, these fish typically inhabit coral reefs and rocky crevices in their natural environment. Their distribution ranges from Bermuda and Florida in the USA to regions in northern South America.
