Congo Tetra

🌈 Congo Tetra – Iridescent Elegance for Community Aquariums

Add graceful motion and shimmering color to your aquarium with the Congo Tetra, a peaceful schooling fish admired for its flowing fins and vibrant, rainbow-like iridescence. Native to the Congo River Basin in Central Africa, these tetras are larger and flashier than your average community fish—making them a favorite for aquarists who want beauty, movement, and harmony in one species.

With proper lighting, their scales reflect hues of blue, violet, orange, and gold, and males develop long, trailing fins that flutter like banners in the current. Best kept in groups of 5 or more, Congo Tetras create an impressive display in planted tanks and large community setups.

🐟 Species Profile:

• Scientific Name: Phenacogrammus interruptus

• Size: 3–3.5 inches (males may reach 4”)

• Temperament: Peaceful, active, schooling

• Tank Size: 30+ gallons (longer tanks preferred)

• Water Parameters: 74–82°F | pH 6.2–7.5 | Soft to moderate hardness

• Diet: Omnivore – accepts flakes, pellets, brine shrimp, bloodworms, and daphnia

🤝 Recommended Tank Mates:

Congo Tetras do best with other peaceful and semi-active species such as:

• Rainbowfish

• Angelfish

• Corydoras Catfish

• Dwarf Gouramis

• Swordtails, Mollies, Rasboras, and larger Tetras

Avoid fin-nippers and overly aggressive tank mates that may damage their long fins or outcompete them for food.

These fish are most impressive under soft, slightly tannin-stained water with dark substrate and moderate plant cover. When cared for properly, they live for years and become even more vibrant with age.
