Golden Tetra (Hyphessobrycon moniliger)
Golden Tetras are very beautiful and peaceful fish and are somewhat rare in the aquarium hobby. These Tetras will suit both a nano tank or a community aquarium, making them a good choice for an aquarist.
These Tetras are a temperate shoaling species, ideal for mature softwater aquariums. It is recommended that you keep Golden Tetras in a group of six or more individuals as this will not only make the fish feel more secure but will result in a far more natural-looking and effective shoal.
Golden Tetra tankmates should also be small and peaceful, as these fish are easily intimidated by more significant or more boisterous species. Ideal tankmates could include other similarly sized Characids, small Dwarf Cichlids, Pencilfish Corydoras Catfish, and some smaller Suckermouth Catfish.
Golden Tetras fare better in an established, well-furnished aquarium. For example, a natural-looking arrangement might consist of a soft, sandy substrate with driftwood branches and roots and bogwood placed to form many shady spots. Aquatic plants, including floating plants, should also be added.
Adding dried leaves such as oak or Indian almond would further emphasise the natural feel and allow the growth of beneficial microbe colonies as decomposition occurs. These microbes can provide an important secondary food source for babies, whilst the tannins and other chemicals discharged by the rotting leaves are viewed as beneficial.
The Golden Tetras head and the lateral surface of the stomach region is a light golden colour. Their eyes are light orange, with the upper one third being red. The sides of their bodies are yellowish, and their caudal peduncle displays a dark blotch. The pelvic fin and the tip of the anal fin are reddish-orange, the caudal and dorsal fins are whitish-grey, and the other fins are pale orange. However, some individuals have reddish dorsal, caudal and anal fins.

Photos of the Golden Tetra
Golden Tetras are endemic to the middle Rio Araguaia and Rio Tocantins Basin in Central Brazil in South America. They inhabit shallow, slow-moving waters with woody areas of fallen branches and roots. Due to the slow release of organic acids and tannins from decaying plant material, the water is typically stained brown. These habitats are usually full of aquatic plants and generally are underneath overhanging riparian vegetation.
What to feed the Golden Tetra
In the aquarium, Golden Tetras are easily fed. However, for the best condition and colours of your fish, you should offer them frequent meals of small live, frozen and freeze-dried foods such as mosquito larvae, bloodworm and vitamin-enriched daphnia and artemia. It would be best to supplement this with good quality dried food such as flakes, micropellets and granules and only feed your Tetras twice daily, providing only what they can consume within 3 minutes or less.
How to sex the Golden Tetra
It is pretty straightforward to differentiate between the male and female Golden Tetra. The males are a little larger, have slender bodies and are slightly more vibrantly coloured than the females. The males also have more prominent finnage. In contrast, the females are more robust, have more rounded bodies than the males and are slightly smaller.
How to breed the Golden Tetra
Unfortunately, there is not much information on how to breed this species. However, these Tetras will more than likely breed in a similar fashion to other Hyphessobrycon species.
Golden Tetras are egg-scattering free spawners that exhibit no parental care. Adult fish in good condition may spawn in a community tank, and even small fry numbers may start to appear.
However, If you would like to raise a decent number of fry, you will require a separate breeding tank. The tank should be dimly lit, and the base needs to have some mesh or bundles of fine-leaved plants like java moss; this will protect the eggs from the adults.
Their water should be soft, slightly acidic to neutral, and the temperature needs to be between 79 and 82 degrees Fahrenheit. You will also need to provide very gentle filtration through an air-driven sponge filter, and dedicated lighting will not be required as eggs and fry can be a little sensitive to light.
You can breed Golden Tetras in pairs or small groups; however, make sure you remove the adults after spawning; otherwise, they may consume the eggs. These Tetras can lay up to a few hundred eggs.
Once the eggs have hatched, the babies will feed on their yolk sacs for a short period. Once the babies become free-swimming, you will need to provide them with microscopic foods such as infusoria and Paramecium. As they develop, you should then offer them microworm or baby brine shrimp.
