The Hummingbird Tetra (Trochilocharax ornatus) is a captivating and rare freshwater fish species native to Peru. Its common name derives from its vibrant colors and dynamic swimming behavior, reminiscent of a hummingbird.
Size: Mature individuals typically reach up to 2 cm (0.8 inches) in length.
Appearance: They possess shimmering, transparent bodies with hues of blue and red. Males are generally larger and more vividly colored than females, often displaying extended fins and a distinctive pouch scale on the caudal peduncle.
Hummingbird Tetras are indigenous to blackwater environments in Peru, particularly around Iquitos. These habitats are characterized by clear, tannin-stained, acidic waters with minimal hardness and conductivity. The substrates typically consist of sand or mud, interspersed with submerged branches, tree roots, and dense leaf litter.
Tank Setup: A well-structured aquarium with a sandy substrate, driftwood roots, and branches is ideal. Adding dried leaf litter can enhance the natural feel and provide additional cover.
Water Conditions: Maintain temperatures between 20–28 °C (68–82 °F), pH levels of 4.0–6.5, and hardness from 18–143 ppm.
Lighting: Soft, dim lighting is preferred. Incorporating aquatic plants like Microsorum, Taxiphyllum, or Cryptocoryne species can provide necessary cover and aesthetic appeal.
Diet: In the wild, they are micropredators, feeding on tiny invertebrates and zooplankton. In captivity, they accept appropriately sized dried foods but thrive on small live and frozen fare such as Artemia nauplii, Daphnia, Moina, and grindal worms.
Social Behavior: They are peaceful but best kept in groups of 8–10 to reduce shyness and encourage natural behaviors. While not ideal for general community tanks due to their size and specific needs, they can coexist with other diminutive, non-aggressive species. Breeding
Breeding in captivity has been achieved, though detailed information is limited. They practice internal fertilization, with both males and females possessing distinctive genital papillae. In well-structured, mature aquariums, small numbers of fry may appear without intervention.
In summary, the Hummingbird Tetra is a unique and delicate species that requires specific care to thrive in captivity. Their enchanting appearance and behavior make them a prized addition for aquarists who can meet their specialized needs
