General: The Congo Tetra is a fish from the slower moving tributaries and marshes of the Congo Basin. This community fish is desirable throughout the hobby due to its peaceful nature and impressive 5 year lifespan. The Congo Tetra is a great addition to any planted tank. This fish will stand out with its elegant fins and unique coloration.
Fecundity (Reproduction): Female Congo Tetra can lay up to 300 eggs per clutch. To encourage breeding behavior, maintain a slightly acidic pH of approximately 6.5 with a water hardness between 1-3 dGH, and a water temperature of 80 degrees Fahrenheit.
Preferred Water Chemistry: Slightly acidic (6.5 to 7.2 pH), soft water hardness (3-12 dGH)
Aquarium Diet: Brine shrimp, blackworms, general flakes, omnivore pellets, and Spirulina
Dimorphism: The Congo Tetra male develops an elongated dorsal, pelvic, anal, and caudal fin to attract females. The male develops a blue shimmer and a more noticeably yellow lateral line. The male also reaches a length of up to four inches. The female will maintain short fins, a tannish brown coloration, and only reach a length of up to three inches.
Compatibility: The Congo Tetra should be kept with other fast swimmers, as it takes only a brief moment to completely consume whatever food has entered the aquarium. The Congo Tetra typically makes a great companion for other large Tetra, South American Dwarf Cichlids (Ram, Apistogramma, Kribensis), Hump-Headed Glassfish, Corydoras, and Rasbora. Ideally, it is best to add fish of a similar size to the species already existing in the aquarium.
