Congo Tetra: A Stunning Addition to Your Freshwater Aquarium

The Congo Tetra (Phenacogrammus interruptus) is a vibrant and peaceful freshwater fish that captivates aquarium enthusiasts with its shimmering colors and graceful swimming. Known for its striking iridescent blue and purple hues, this species is a popular choice among hobbyists seeking both beauty and community-friendly temperament.

Size and Appearance

Congo Tetras typically grow to about 3 to 3.5 inches (7.5 to 9 cm) in length, making them a medium-sized tetra species ideal for community tanks. Males are generally larger and exhibit more intense coloration and longer fins compared to females. Their unique metallic sheen and flowing fins add elegance to any aquarium setup.

Temperament and Behavior

Renowned for their peaceful and social nature, Congo Tetras thrive in groups of six or more. They are schooling fish that enjoy swimming together, which helps reduce stress and showcases their natural behavior. They coexist well with other non-aggressive species, making them excellent candidates for community aquariums.

Tank Size and Setup

A minimum tank size of 30 gallons is recommended to provide ample swimming space and to accommodate a healthy school. Congo Tetras prefer a well-planted aquarium with plenty of hiding spots, driftwood, and moderate water flow that mimics their natural riverine habitat. A dark substrate can enhance their vibrant coloration, creating a stunning visual effect.

Water Parameters

• Temperature: 73°F to 82°F (23°C to 28°C)
• pH: 6.0 to 7.5
• Water Hardness: Soft to moderately hard (3 to 15 dGH)

Maintaining stable water conditions is essential for their health and coloration. Regular water changes and proper filtration will keep your Congo Tetras thriving.

Diet and Feeding

Congo Tetras are omnivores and have a varied diet in the wild. In captivity, they readily accept high-quality flake food, pellets, and frozen or live foods such as bloodworms, brine shrimp, and daphnia. Offering a diverse diet ensures vibrant coloration and supports their active lifestyle.

Compatibility with Other Fish

Thanks to their peaceful temperament, Congo Tetras are compatible with other similarly sized, non-aggressive fish such as rasboras, guppies, corydoras catfish, and dwarf gouramis. Avoid housing them with large or aggressive species that may bully or outcompete them for food.
