Werner's Tetra

Geographical Origin and Habitat: Native to the calm waters of the Guamá River basin in northern Brazil. It inhabits slow-moving forest streams characterized by soft, acidic water and leaf litter.

Taxonomy and Morphology: Belongs to the Characidae family. Features a laterally compressed body, typical of small Hyphessobrycon species. Adults reach a maximum length of about 3.5 cm.

Social Behavior: Peaceful and shy schooling fish. Must be kept in groups of at least 8 individuals to encourage natural shoaling behavior and minimize stress.

Coloration and Sexual Dimorphism: Displays silvery and pinkish body reflections, with a lightly tinted caudal fin. Adult males have slightly more elongated fins, while females are noticeably rounder.

Aquarium Setup: Requires a well-planted aquarium of at least 60 liters, with shady areas provided by floating plants and driftwood. Dark sand is the ideal substrate.

Diet and Feeding: Omnivorous. Accepts high-quality micro pellets or flakes, but benefits greatly from live or frozen foods such as baby brine shrimp and daphnia.

Water Quality: Prefers soft, acidic water. Keep pH between 5.5 and 7.0, and GH between 2 and 10. Gentle filtration is ideal as they dislike strong currents.

Compatibility and Cohabitation: Exceptionally peaceful. Compatible with other small characins, dwarf corydoras, and pencilfish. Avoid large or aggressive tankmates that could prey on them.

Aquarium Breeding: Egg-scatterer. Successful breeding requires very soft, acidic water and the use of spawning mops or fine mosses in a separate breeding tank.

Risks and Diseases: Sensitive to rapid temperature changes and nitrate build-up. Moderate jump risk; a secure aquarium lid is highly recommended.
