Since they are active schooling fish, a longer aquarium is preferred so they have enough room to swim naturally. For the best color and comfort, create a natural planted tank with live aquarium plants, driftwood, smooth substrate, and slightly dim lighting. Floating plants and botanical leaves can help soften the light and make Congo Tetras feel more secure. How Many Congo Tetras Should You Keep? Congo Tetras should be kept in a group of at least 6 or more. A larger school will help reduce stress, improve confidence, and create a more impressive display in the aquarium. When kept alone or in very small numbers, they may become shy or stressed. Compatible Tank Mates The Congo Tetra is a peaceful community fish that pairs well with other calm, similar-sized freshwater species. Good tank mates may include peaceful tetras, rainbowfish, corydoras, dwarf cichlids, angelfish with caution, peaceful barbs, gouramis, and other non-aggressive community fish. Avoid housing Congo Tetras with fin-nipping fish, overly aggressive species, or very small fish that may feel stressed by their active swimming behavior. Feeding Guide Congo Tetras are omnivores and should be fed a varied diet to support strong color, healthy growth, and active behavior. Offer high-quality flakes or small pellets as a staple food, then rotate with frozen or live foods such as brine shrimp, bloodworms, daphnia, and mosquito larvae. Feed small portions once or twice daily, only giving what they can finish within a short time. A clean diet and stable water quality will help bring out their best color. Important Care Notes Keep Congo Tetras in groups of 6 or more. Provide open swimming space with planted areas for cover. Use peaceful tank mates only. Avoid fin-nipping fish that may damage their flowing fins. Maintain stable water quality for best color and long-term health. Color may vary depending on age, sex, diet, stress level, and aquarium lighting. Order Congo Tetra Fish Online Add color, movement, and elegance to your freshwater aquarium with the Congo Tetra Fish.
