General Description
The African Red-Eyed Tetra, scientifically known as Arnoldichthys Spilopterus, is a monotypic genus and species characterized by its large scales compared to most relatives, earning it nicknames like the 'large-scaled African characin' or 'Niger tetra.' This hardy fish, endemic to Nigeria, can live for several years if properly cared for and reaches a maximum size of 10.0cm.
Aquarium Setup
To create an ideal habitat for the African Red-Eyed Tetra, a tank of at least 160 litres should be equipped with driftwood branches, roots, smooth stones, and aquatic plants while maintaining ample open space for this active species. Filtering over peat can mimic its natural waters, which are often tinged with tannins from organic decay. (see table)
Behaviour
This species is peaceful yet highly active, making it unsuitable for tanks with timid fish. Preferring a West African-themed community tank, they thrive alongside other Alestiidae tetras, small Synodontis species, and robust dwarf cichlids like Pelvicachromis pulcher. African Red-Eyed Tetras are schooling fish, with this behavior diminishing as they age.
Feeding and Diet
The African Red-Eyed Tetra is an unfussy eater, accepting various foods. It particularly enjoys small live and frozen foods, aiding in maintaining optimal health and condition.
Reproduction & Dimorphism
While not challenging to breed, the African Red-Eyed Tetra's spawning is rarely attempted. Best results are achieved by conditioning the fish with live and frozen foods, selecting the most colorful male and fattest female, and placing them in a separate aquarium with a mesh base to prevent egg predation. Males exhibit slightly more coloration, dark stripes in the anal fin, and a slimmer body compared to mature females. (see table)
Habitat and Distribution
In the wild, the African Red-Eyed Tetra is found in streams and rivers within the Ogun and lower Niger river systems in Nigeria. Despite being popular in the aquarium trade, this species remains scarce in the wild, confined to fewer than ten locations facing threats from deforestation and uncontrolled pollution.
