Tetra Electric Green
Hyphessobrycon sp.

Description
The Tetra Electric Green is a stunning and vibrant variety of tetra, known for its bright and electrifying green coloration. The body of the Electric Green Tetra is typically a translucent, pale to medium green, with a distinctive iridescent shine that gives it a glowing, almost neon-like appearance under the right lighting conditions. The fish often has a shimmering metallic finish on its scales, making it stand out in any aquarium. The fins are usually clear or lightly tinted, which creates a beautiful contrast with the electric green body color.
Habitat Origin
Native to South America, particularly found in the freshwater rivers and streams of countries like Brazil. These tetras are typically found in slow-moving, clear waters with abundant vegetation, submerged rocks, and aquatic plants. In the wild, they prefer slightly acidic to neutral waters and are often found in areas with moderate water flow and good oxygenation.
Aquarium
Ideal Number in Aquarium: At least 6-8 individuals to allow them to display their natural schooling behavior and feel secure.
Favorite Food

Electric Green Tetras are omnivores and will accept a variety of foods. They can be fed high-quality flake food, micro pellets, and live or frozen foods such as brine shrimp, daphnia, bloodworms, and grindal worms. They will also enjoy some vegetable-based foods, such as spirulina, blanched zucchini, and lettuce. A varied diet will help maintain their health and vibrant coloration.
Behavior:
Electric Green Tetras are peaceful and active fish that thrive in schools. They are social fish, often seen swimming together in coordinated groups in the middle and upper levels of the tank. They are non-territorial and get along well with other peaceful species, making them perfect for community aquariums. They do, however, tend to be a bit shy when first introduced to a new environment. To help them feel secure, it’s best to provide plenty of hiding spots, plants, and decorations.
Special Care:
Tetra Electric Green is relatively easy to care for, but they do require stable water conditions. Regular water changes, good filtration, and a well-maintained tank are necessary to keep them healthy. They enjoy aquariums with plenty of plants, which also provide hiding spots for them. A fine, soft substrate such as sand or smooth gravel is ideal for these fish, as they tend to forage along the bottom of the tank for food.
Compatibility with Other Fish:
Electric Green Tetras are compatible with a wide variety of peaceful species. They can be kept with other tetras, rasboras, gouramis, corydoras catfish, and peaceful shrimp. They are perfect for community tanks, as their gentle nature ensures they will coexist with other small, non-aggressive species. It is best to avoid keeping them with larger or more aggressive fish, as they may become stressed or harassed.
Breeding Setup
A separate breeding tank of at least 40 liters (10 gallons) is strongly recommended for Tetra Electric Green. These peaceful fish can become stressed in community settings, so a dedicated tank offers better control over water quality and ensures the fry’s safety. Maintain water at pH 6.0–7.5, temperature 24–28°C, and hardness 6–12 dGH. Use a sponge filter or low-flow internal filter to avoid strong currents and protect fry from being sucked in. Substrate should be fine gravel or sand, and adding plants like Java moss, Anubias, or floating plants provides egg-laying sites and helps reduce stress. Use moderate lighting with a 10–12 hour cycle.
Conditioning for Breeding
Prepare the breeders with a high-protein, varied diet, including live or frozen foods such as brine shrimp, daphnia, and bloodworms. Supplement with high-quality tetra flakes or pellets. Regular 20–30% water changes per week will help maintain water quality and simulate natural breeding triggers. Slightly raise the temperature to 28°C (82°F) to encourage spawning.
Spawning Process
When conditioned and placed in optimal water conditions, males will intensify their color and begin courtship. Females lay 50–200 eggs on flat surfaces like plant leaves, rocks, or aquarium glass, which are fertilized immediately by the male. Once spawning is complete, remove the parents promptly to prevent them from eating the eggs. This also ensures a calmer environment for hatching.
Fry Care
Eggs hatch in about 2–4 days, depending on water temperature. Once fry absorb their yolk sacs (usually by day 2–3), begin feeding them infusoria, liquid fry food, or finely crushed flakes. After a week, introduce newly hatched brine shrimp or microworms to support faster growth. Maintain high water quality with 10–15% water changes every 2–3 days, stable temperature, and minimal water flow. Provide hiding spots like plants or moss to keep the fry secure.
Additional Notes
Tetra Electric Green reach breeding maturity at 6–9 months of age. Males are usually smaller and more vibrant, especially during courtship, while females are larger, rounder, and less colorful. To avoid stress, do not overcrowd the tank, maintain stable parameters, and remove aggressive tankmates. A calm, consistent environment is key to successful breeding and fry development.
