Gold Tetra

Geographical Origin and Habitat: Distributed throughout northern South America, including the Amazon and Orinoco basins and coastal rivers of the Guianas. Inhabits sluggish forest streams and coastal swamps, often in blackwater.

Taxonomy and Morphology: A member of the Characidae family. Features a typical tetra silhouette, reaching a maximum length of 4.0 cm.

Social Behavior: Highly peaceful and gregarious. It must be kept in a group of 8-10 or more to form a cohesive and beautiful school, which reduces stress.

Coloration and Sexual Dimorphism: Famous for its bright metallic gold sheen, which in the wild is a defense mechanism secreting guanine against minor skin parasites. Tank-bred specimens lack this sheen, showing a silvery-grey body with red fin bases. Females are deeper-bodied.

Aquarium Setup: An 80-liter tank with dark substrate, peat filtration, and driftwood roots. Subdued lighting via floating plants is recommended to simulate a forest stream environment.

Diet and Feeding: Omnivorous. Readily accepts flakes, small pellets, and freeze-dried foods. Supplement with live or frozen daphnia, cyclops, and brine shrimp.

Water Quality: Prefers soft, slightly acidic water. Keep temperature at 24-28 °C, pH 6.0-7.5, and hardness at 2-12 dGH.

Compatibility and Cohabitation: Ideal for community aquariums. Excellent companions include other small tetras, pencilfish, corydoras catfish, and peaceful dwarf cichlids.

Aquarium Breeding: Egg scatterer. Requires soft, acidic water and spawning mops or fine plants. Remove the adult pair immediately after egg-laying to prevent predation.

Risks and Diseases: Prone to white spot disease (ich) if subjected to sudden temperature drops or high ammonia/nitrite levels.
