Hemigrammus rodwayi, commonly known as the Gold Tetra, is a small, schooling freshwater fish belonging to the family Characidae. It is characterized by its distinctive golden-yellow to brassy coloration, often with a subtle iridescent sheen, particularly along the lateral line. This species is known for its peaceful demeanor and active swimming habits, making it a popular choice for community aquariums. While not as brightly colored as its more famous relative, the Neon Tetra (Paracheirodon innesi), the Gold Tetra possesses a unique understated elegance. They are typically found in blackwater or clearwater streams with dense vegetation and submerged roots in their native South American habitats.

Tips Identifikasi
Coloration
Look for the characteristic golden-yellow to brassy body color, which can appear iridescent under certain lighting conditions. This is the primary distinguishing feature from other tetras.
Size and Body Shape
Observe its small, elongated, yet relatively deep body shape, typically reaching up to 4.5 cm. This helps differentiate it from more slender or larger tetra species.
Absence of prominent stripes/spots
Unlike many other tetras (e.g., Neon Tetra, Cardinal Tetra), Hemigrammus rodwayi lacks prominent bright red or blue stripes, or distinct black spots on its body, relying instead on its overall golden hue.
Adipose Fin
Confirm the presence of a small adipose fin, a common feature among characins, to help confirm its family classification.
Habitat

- freshwater
- Kedalaman
- Typically found in shallow, slow-moving waters near the banks.
- Lingkungan
- Inhabits blackwater and clearwater streams, tributaries, and flooded forest areas. Prefers areas with dense aquatic vegetation, submerged roots, leaf litter, and overhanging terrestrial vegetation, which provide shelter and foraging opportunities. The water is often soft and acidic.
- Sebaran geografis
- Native to South America, primarily found in the Guianas (Guyana, Suriname, French Guiana) and parts of the lower Amazon basin in Brazil. Specifically, it is found in river systems such as the Essequibo, Corantijn, and Maroni rivers.

Fakta kunci
Golden Glowinteresting
The 'Emas' in 'Neon Tetra Emas' is Indonesian for 'gold', accurately describing its primary coloration, though it's not a true Neon Tetra (Paracheirodon innesi).
Schooling Behaviorbehavior
Gold Tetras are highly social fish and thrive in large schools. Keeping them in groups of 6 or more significantly reduces stress and encourages their natural behaviors, making them more vibrant and active.
Habitat Mimicryinteresting
To best replicate their natural blackwater or clearwater habitats, aquarists often use dark substrates, driftwood, and dried leaves (like Indian almond leaves) to release tannins, which slightly acidify the water and enhance the fish's coloration.
Dietary Flexibilitybehavior
As omnivores, Gold Tetras are not picky eaters and will readily accept a variety of foods, including high-quality flakes, micro-pellets, and small live or frozen foods like daphnia, brine shrimp, and bloodworms.
