Care

Due to its rarity and specialized habitat requirements, the Black Brotula is not typically kept by hobbyists. If one were to attempt to keep this species, it would require a very deep and large aquarium with minimal lighting to mimic its natural deep-sea environment. The tank would also need to be equipped with a chiller to maintain the low temperatures that this species is accustomed to.

Reproduction

Little is known about the reproductive habits of the Black Brotula in the wild or in captivity. It is presumed that, like many deep-sea fish, they have specific and possibly complex breeding behaviors that are not well understood.

Habitat

Stygnobrotula latebricola is found in the deep waters of the Atlantic Ocean, typically at depths exceeding 1,000 meters. It inhabits the benthic zone, living among the sea floor's sediments and rocks where it can find shelter and hunt for its prey.
