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

Albino Congo Tetras are a pale ornamental form of the Congo Tetra, with a creamy silver to yellowish body, red or pink eyes and translucent fins. Their reduced pigmentation gives them a striking appearance, while the species retains the elegant, laterally compressed body shape associated with Congo Tetras.

As they mature, they develop flowing fins and a subtle iridescent sheen that can appear blue, violet, gold or green depending on the light. Adult males are particularly impressive, with extended dorsal, caudal and fin filaments that give the fish a graceful, shimmering profile.

These are active but generally peaceful midwater fish. They spend much of their time moving through the open water as a group, communicating through displays and changes in position rather than showing the persistent fin-nipping behaviour associated with some smaller, more boisterous tetras.

In the wild, Congo Tetras inhabit clear to lightly stained waters beneath the cover of overhanging rainforest vegetation. Their natural environment is rich in subdued light, submerged structure and plant material, and the albino form shares the same social and behavioural characteristics as the normally pigmented variety.

Albino Congo Tetras are an albino colour form of the Congo Tetra, Phenacogrammus interruptus, which originates from the Congo River Basin in Central Africa. Wild Congo Tetras are associated with forest streams, tributaries and other relatively soft, shaded freshwater habitats in the Democratic Republic of the Congo and surrounding basin.

A group of Albino Congo Tetras should be given at least a 120-litre aquarium, with a footprint of approximately 120 cm by 40 cm so they have enough uninterrupted swimming space. Use a fine, dark substrate with robust plants around the sides and back, leaving an open central area for shoaling. Driftwood, roots and floating plants can provide shade and security, while gentle to moderate water movement and subdued lighting create a natural-looking environment. A secure lid is advisable because active Congo Tetras may jump.

Adult Albino Congo Tetras can reach approximately 8 cm (3.1 in), although males may grow to around 10 cm (3.9 in) including their extended fins. Females are usually shorter and more robustly built than males.

Albino Congo Tetras are omnivorous and benefit from a varied diet. Offer a quality small pellet or flake as a staple, supplemented with frozen or live foods such as daphnia, mosquito larvae, brine shrimp and bloodworm. Occasional finely crushed vegetable matter or spirulina-based foods can add variety, while small portions fed regularly help support their colour, growth and fin development.

Albino Congo Tetras are peaceful community fish and suit similarly sized, calm tankmates such as peaceful barbs, larger rasboras, rainbowfish, peaceful gouramis, dwarf cichlids and other non-aggressive African tetras. They should be kept away from fin-nipping species, highly aggressive cichlids and very small fish that may be intimidated by their size and activity. Long-finned males can also be vulnerable to persistent nipping, so tankmates should be selected carefully.

Albino Congo Tetras are egg-scattering free spawners that can be bred in a separate, mature spawning aquarium. Condition a group with plenty of live or frozen foods, then provide soft, slightly acidic water and fine-leaved plants or a spawning mop. Spawning usually takes place among the vegetation, with eggs scattered over the substrate. Remove the adults after spawning, as they may eat the eggs. The eggs generally hatch within several days, and the tiny fry initially require infusoria-sized foods before progressing to newly hatched brine shrimp.

Males are generally larger and more brightly iridescent, with longer, more flowing dorsal, caudal and fin filaments. Females are typically smaller, deeper-bodied and have shorter, less elaborate fins.
