Goldspotted Tetra - Hyphessobrycon griemi Fish Profile & Care Guide
Introduction
The Goldspotted Tetra (Hyphessobrycon griemi) is a small freshwater fish from the Characidae family. Native to South America. These Tetras are a peaceful and social species, often kept in community aquariums due to their calm temperament and attractive appearance. The fish typically grows to around 3 to 4 cm in length and exhibits a silvery body with subtle iridescent hues, making it a visually appealing addition to tanks.
Goldspotted Tetras are best kept in groups as a schooling fish to encourage natural behaviour and reduce stress. When selecting Goldspotted Tetras tankmates, opting for small, peaceful species that will not cause stress or intimidation is essential. Suitable companions include dwarf cichlids, Corydoras catfish, smaller species of suckermouth catfish, and pencilfish.
To create optimal habitat for Goldspotted Tetras, it is recommended that an aquarium with mature, well-aged water enriched with ample driftwood be established to provide shaded areas. The gradual release of tannins from the driftwood aids in acidifying the water, giving it a natural, translucent, tea-coloured tint. Peat filtration can achieve the desired pH levels to enhance these water conditions further.
Introducing a moderate amount of aquatic plants will contribute to the tetras' sense of security and promote overall well-being. Maintaining subdued lighting is important, with tannins and floating plants helping to diffuse bright light. Additionally, darker substrates and background elements will highlight the vibrant colours of the Goldspotted Tetras, enhancing their visual appeal within the aquarium.

Sexual Dimorphism
Distinguishing between male and female Goldspotted Tetras is relatively straightforward. Males are generally smaller and more slender, while females tend to be larger and have a fuller, more rounded body shape. The more robust build of the females is particularly noticeable during the breeding season when they carry eggs.

Natural Habitat
Goldspotted Tetras are native to the eastern coastal rivers of Brazil, ranging from São Paulo to northern Santa Catarina. They inhabit slow-moving waters with dense aquatic vegetation and sandy or muddy substrates. These environments are typically shaded by overhanging foliage, resulting in a dimly lit, tranquil habitat that closely mimics the tetras' natural ecosystem.
Breeding
The Goldspotted Tetra is a prolific egg-scattering free spawner, exhibiting no parental care during breeding. Under favourable conditions, healthy adult fish may spawn in a community tank, occasionally leading to the appearance of a few fry. However, for those seeking a larger yield of fry, it is essential to establish a dedicated breeding tank.
The breeding tank should feature subdued lighting and a substrate of fine mesh or clumps of fine-leaved plants, such as Java moss, to protect the eggs from adult predation. The water should be slightly acidic to neutral, soft, and maintained at a temperature of 79–82°F (26–28°C). Direct lighting is unnecessary, as both eggs and fry are light-sensitive. When breeding, pairing or using small groups of Goldspotted Tetras is advisable. Once spawning is complete, the adults must be promptly removed to avert them from consuming the eggs.
Goldspotted Tetras can lay several hundred eggs. After hatching, the fry will rely on their yolk sacs for nourishment before becoming free-swimming. At this point, providing microscopic food sources such as infusoria or Paramecium is crucial. As the fry grows, transitioning to slightly larger live foods like microworms or baby brine shrimp will support healthy development.
Diet & Feeding
The Goldspotted Tetra is a versatile species with a broad acceptance of various food sources. While they readily consume a range of nourishment, it is vital to provide a balanced diet consisting of high-quality dried foods such as micropellets, flakes, and granules, supplemented with live or frozen options like vitamin-enriched brine shrimp, bloodworms, white mosquito larvae, and daphnia. For optimal health and vitality, it is recommended that Goldspotted Tetras be fed once or twice daily, presenting only what they can consume within three minutes. This feeding schedule ensures that they receive adequate nutrition while preventing the risks associated with overfeeding.
