The Congo tetra (Phenacogrammus interruptus) is a freshwater fish species native to the Congo River basin in Central Africa. It is a popular choice for aquarium enthusiasts due to its stunning coloration, peaceful nature, and active swimming behavior.
Congo tetras have a distinctive elongated body shape, growing up to about 3.5 inches in length. The males have a striking iridescent blue-green coloration on their upper body, while the lower body and fins are typically reddish-orange or yellow. Females have a less vibrant coloration, with a more muted green-blue upper body and yellowish lower body and fins.
In the wild, Congo tetras inhabit rivers and streams with slow to moderate water flow and plenty of vegetation. In the aquarium, they require similar conditions with soft, slightly acidic water and plenty of plants to provide cover and hiding places.
Congo tetras are peaceful and can be kept in a community aquarium with other small to medium-sized non-aggressive fish species. They are omnivorous and will readily accept a variety of foods, including flakes, pellets, frozen or live foods such as brine shrimp, bloodworms, and daphnia.
Overall, the Congo tetra is a beautiful and peaceful fish species that is relatively easy to care for and suitable for aquarium enthusiasts of all levels.
