Stygnobrotula

Stygnobrotula latebricola

Bohlke, 1957

Black Widow

Likely Reef Tank Suitable

Likely Fish-Only Tank Suitable

Range: Western Atlantic Ocean: Southern Florida and the Bahamas, south to Curacao.

Size: 3 inches (7 cm)

Natural Environment: Inhabits reef crevices, coral heads and small caves at depths between 3 - 50 feet (1 - 15 m) and feeds on small fishes and benthic invertebrate.

General Husbandry: Very secretive and very rarely seen in the trade, having a completely black body and fins.

Best maintained in small reef or fish-only aquariums with several hiding places, as it’s quite shy. In fact, its owner may never see it again if there are many hiding places!

As to diet, it can be fed enriched live adult brine shrimp or a wide variety of frozen or fresh finely chopped meaty foodstuffs. Should be fed at least once per day, usually during evening hours when the aquarium is in darkness. (Use a red light to find the location of the fish, and then offer it the food).
