The Red-base Tetra, scientifically known as Hemigrammus stictus, is a charming and colorful species of freshwater fish found in the slow-moving rivers and streams of South America, particularly in the Amazon Basin. This tetra is appreciated for its striking appearance and peaceful temperament, making it a delightful addition to community aquariums.

Red-base Tetras have a slender, laterally compressed body that typically displays a silver or transparent base color. Their most distinctive feature is the bright red patch located at the base of their tail fin, which stands out beautifully against their otherwise subtle coloration. Additionally, they often have a hint of green or blue iridescence along their bodies, which can be more noticeable under proper lighting. Their fins are usually clear with a slight tint, adding to their delicate appearance.

In captivity, Red-base Tetras thrive in a well-planted aquarium that mimics their natural habitat. The tank should include plenty of live plants such as Java moss, Amazon swords, and floating plants to provide cover and create a comfortable environment. Driftwood and leaf litter can also be added to replicate the tannin-rich waters of their native habitat. A dark substrate will enhance their colors and make them feel more secure.

These tetras are social, schooling fish and should be kept in groups of at least six or more. Keeping them in a school not only reduces stress but also encourages natural behavior and enhances their visual appeal as they swim together. They are peaceful and make excellent tank mates for other small, non-aggressive fish, making them ideal for community tanks.

The diet of Red-base Tetras should be varied to ensure they receive all the necessary nutrients. They readily accept high-quality flake foods, micro pellets, and live or frozen foods such as brine shrimp, daphnia, and bloodworms. Providing a mix of these foods will help maintain their health and vibrant colors.

Breeding Red-base Tetras in captivity can be a rewarding experience. They are egg scatterers, typically laying their eggs among fine-leaved plants. To encourage breeding, the water should be slightly acidic and soft, with a stable temperature. Conditioning the breeding pair with high-quality live or frozen foods can increase the likelihood of spawning. After spawning, it is advisable to remove the adults to prevent them from eating the eggs. The eggs usually hatch within a few days, and the fry can be fed with infusoria or finely crushed flake food until they are large enough to accept standard fare.

Overall, the Red-base Tetra is an excellent choice for both novice and experienced aquarists. Their striking red coloration, peaceful nature, and ease of care make them a delightful addition to any well-maintained community aquarium. With proper care and the right environment, they can thrive and bring a touch of vibrant beauty to your aquatic setup.
