Golden Blue Emperor Tetra (Nematobrycon palmeri var. “Golden Blue”) Care Guide:
The Golden Blue Emperor Tetra is a stunning color variant of the Emperor Tetra, known for its metallic golden body with subtle blue iridescence and graceful swimming. Native to Colombia’s slow-moving, shaded streams, it thrives in well-planted aquariums with subdued lighting and gentle flow. A peaceful schooling species, it should be kept in groups of six or more in a minimum 20-gallon tank to reduce stress and encourage natural behavior. Ideal water parameters include temperatures of 75–82°F (24–28°C), pH 6.0–7.5, and soft to moderately hard water. They are omnivorous, readily accepting high-quality flakes, micro pellets, and frozen foods like brine shrimp or bloodworms. Males display brighter colors and longer fins, especially during courtship. These elegant tetras make excellent additions to peaceful community aquariums.
