Hemigrammus Boesemani

Datasheet

General Description

The Hemigrammus Boesemani, commonly known as Boesman's Tetra, is a rare species in the aquarium trade, previously considered a subspecies of H. micropterus. Belonging to the Characidae family, this tetra is relatively small, reaching a maximum size of 4.5cm. Its taxonomic status is currently uncertain, with the genus Hemigrammus housing over 70 small characin species.

Aquarium Setup

For optimal care, it is advisable to maintain Boesman's Tetra in groups of at least 6 to encourage their natural shoaling behavior. A tank of at least 70 litres is required. Setting up a biotope simulation involves river sand substrate, driftwood, dried leaves, and twisted roots to mimic their natural habitat. Dim lighting and the addition of aquarium-safe peat to the filter can replicate blackwater conditions, enhancing their well-being.

Behaviour

Characterized as a peaceful species, Boesman's Tetra does best when housed with other South American fish like Hemigrammus or Hyphessobrycon species, dwarf cichlids, and Corydoras. A shoaling species by nature, they thrive in the company of their own kind and in a harmonious community tank with smaller rasboras, barbs, and certain cichlids.

Feeding and Diet

Being omnivorous, Boesman's Tetra accepts a range of foods including dried flakes, granules, live, and frozen foods. A varied diet of small live and frozen foods along with dried flakes and granules is ideal for their nutritional needs.

Reproduction & Dimorphism

Breeding Boesman's Tetra involves setting up a separate tank with specific water conditions (soft, acidic water) and the presence of fine-leaved plants for egg deposition. The breeding can be done in groups or pairs, with proper conditioning and removal of adults post-spawning to prevent egg consumption. Sexing can be determined by examining the swim bladder, which varies in shape between males and females.

Habitat and Distribution

Boesman's Tetra is found in Suriname, French Guiana, and Peru, favoring slow-flowing waters, tributaries, and rivers. While they prefer sluggish environments, they have also been discovered in varied water conditions, posing a geographical distribution puzzle suggesting possible misidentification or undiscovered habitats.
