Golden Congo Tetra Care Guide - Aquarium Tips, Diet & Breeding

The Golden Congo Tetra is a striking African characin with a warm golden to amber body, translucent fins and an attractive metallic sheen. Mature males may develop elongated fin rays and a fuller, more flowing appearance, especially when displaying to females or competing with other males.

These are active, peaceful schooling fish that spend much of their time in the middle and upper areas of the aquarium. In a proper group they are confident and constantly on the move, with males often performing short displays that show off their colours and finnage without causing serious injury.

In the wild, the species is associated with the shaded waterways of the Congo basin. Leaf litter, overhanging vegetation and tannin-stained water create a subdued environment in which the fish's golden colouring catches the available light.

Although less commonly seen than the familiar Congo Tetra, Phenacogrammus aurantiacus is valued for its bright colour, lively behaviour and distinctly African character. Its social nature and elegant appearance make it an appealing choice for a spacious community aquarium.

Golden Congo Tetras are native to the Congo River basin in Central Africa, particularly parts of the Democratic Republic of the Congo. They inhabit warm, slow-moving forest streams and tributaries associated with the basin.

A group should be provided with an aquarium of at least 120 litres, preferably measuring around 90 cm long by 40 cm wide or larger to provide uninterrupted swimming space. Use a dark sand or fine-gravel substrate, areas of dense planting, some driftwood and subdued lighting, while leaving open water at the front and centre. Floating plants can provide shade, and gentle filtration with good oxygenation is appropriate without creating an excessively strong current.

Males can reach about 10 cm (4 inches), while females are usually slightly smaller at around 8 cm (3.2 inches).

Golden Congo Tetras are omnivores and thrive on a varied diet. Offer a quality small-to-medium tropical flake or pellet as a staple, supplemented with frozen or live foods such as bloodworm, brine shrimp, daphnia, mosquito larvae and other small aquatic invertebrates. Regular variety helps maintain their colour, condition and willingness to breed.

Golden Congo Tetras suit peaceful community aquariums containing similarly sized African tetras, peaceful barbs, rasboras, larger danios, rainbowfish and calm Corydoras or other non-aggressive bottom dwellers. They should not be housed with fin-nipping species, highly aggressive cichlids or boisterous fish that will outcompete them. Very tiny fish and slow, long-finned species may also be poor companions because of the Golden Congo Tetra's size and activity level.

Golden Congo Tetras are egg-scattering spawners. Condition a group with plentiful live or frozen foods, then move the adults to a separate spawning aquarium with soft, slightly acidic water and fine-leaved plants or spawning mops. The eggs are scattered among the vegetation, after which the adults should be removed because they may eat them. Hatching usually takes several days, and the tiny fry need suitably small first foods such as infusoria before progressing to newly hatched brine shrimp.

Males are generally larger and more colourful, with longer, more elaborate dorsal, anal and caudal-fin extensions. Females tend to be shorter-bodied, rounder through the abdomen and less dramatically finned.
