Werner's Tetra Breeding Guide
Overview
Werner's Tetra, Hyphessobrycon werneri, is a slim characin from the Guamá River basin in South America, reaching a maximum standard length of about 3.2 cm. FishBase lists its conditions as pH 5.6-7.0, 22-27 °C and hardness 7-20 dH. Like other Hyphessobrycon it is a small egg-scattering tetra.
Breeding Setup
Small Hyphessobrycon are spawned in a separate, dimly lit tank with fine-leaved plants or spawning mops, or a mesh base, so that scattered eggs fall away from the adults. Soft water within the species' reported range of pH 5.6-7.0, 22-27 °C and 7-20 dH is appropriate.
Egg & Fry Care
As an egg-scatterer with no parental care, the adults should be removed after spawning to protect the eggs. Small-tetra fry are reared on infusoria-grade foods before brine shrimp nauplii and microworm. Species-specific hatch times were not recorded in the consulted sources.
