Description
Bleeding Heart Tetra – Hyphessobrycon erythrostigma
Introduction:
The Bleeding Heart Tetra (Hyphessobrycon erythrostigma) is a striking and peaceful freshwater fish, named for the distinctive red patch on its body that resembles a bleeding heart. Native to the rivers of South America, this species is ideal for peaceful community aquariums. Reaching a maximum size of around 2.5 inches, the Bleeding Heart Tetra is a hardy species that adds color and movement to any tank.
1. Natural Habitat and Behavior
- Natural Habitat: Native to the Paraguay River Basin in South America, Bleeding Heart Tetras thrive in warm, slightly acidic waters with dense vegetation. They are typically found in slow-moving waters, such as streams and rivers, where they form schools to navigate through plants and debris.
- Behavior: Bleeding Heart Tetras are peaceful, active fish that do well in schools of 6 or more. They are not aggressive and generally avoid confrontation. They are known for their shy behavior and may initially hide in densely planted areas until they become accustomed to their new environment.
2. Aquarium Setup
- Tank Size: A minimum of 10 gallons is suitable for a small school of Bleeding Heart Tetras. However, a larger tank (20 gallons or more) provides better conditions and space for additional tankmates.
- Substrate: Soft, fine gravel or sand works best for Bleeding Heart Tetras. They are not bottom-dwelling fish, but a fine substrate helps create a natural environment and reduces any irritation to their sensitive bodies.
- Decor: Use dense plants, driftwood, and rocks to replicate their natural environment. The plants provide shelter, and floating plants can help diffuse light, creating a shaded area. Open swimming spaces should also be provided, as Bleeding Heart Tetras prefer to move freely through the tank.
- Water Conditions: These tetras prefer slightly acidic to neutral water, with a pH of 6.5 to 7.5. The water temperature should be between 72°F and 82°F (22°C to 28°C), with a water hardness of 4-12 dGH. Regular water changes and a good filtration system are important to maintain water quality.
- Lighting: Moderate lighting is suitable, and soft, diffused light is ideal for enhancing the fish’s vibrant colors. Floating plants can also be added to create shaded areas where the tetras feel secure.
3. Diet and Feeding
- Diet: Bleeding Heart Tetras are omnivorous, thriving on a balanced diet of high-quality flake food, pellets, and live or frozen foods like brine shrimp, daphnia, and bloodworms. They are not picky eaters and will accept a variety of food types.
- Feeding Schedule: Feed Bleeding Heart Tetras twice a day, offering only as much food as they can consume in a few minutes. Overfeeding can pollute the water, so ensure to remove any uneaten food. A varied diet will help maintain their health and enhance their coloration.
4. Compatibility with Other Fish
- Compatible Species: Bleeding Heart Tetras are peaceful and work well in community tanks with other non-aggressive species such as Corydoras catfish, other small tetras, guppies, and rasboras. They thrive when kept in schools of at least 6 fish and can share a tank with many species without conflict.
- Incompatible Species: Avoid keeping Bleeding Heart Tetras with aggressive or fin-nipping species. Cichlids or large predatory fish may harm them, so choose tankmates that are similar in size and temperament.
5. Common Challenges and Tips
- Schooling: Like most tetras, the Bleeding Heart Tetra is a schooling fish. It is best to keep them in a group of at least 6 to reduce stress and encourage natural behaviors. A lone tetra may become shy and inactive.
- Water Quality: Bleeding Heart Tetras are sensitive to water quality. Regular water changes (around 25% per week) are recommended to keep their environment clean. Use a gentle filtration system to avoid strong currents that may stress the fish.
- Aggression: While not aggressive, the Bleeding Heart Tetra may become stressed if housed with overly boisterous or territorial species. Keep them with similarly calm species to ensure a peaceful tank environment.
Conclusion:
The Bleeding Heart Tetra (Hyphessobrycon erythrostigma) is an attractive and peaceful species that thrives in schools. With its easygoing nature and vibrant colors, it is a great addition to a community aquarium. By maintaining the proper water conditions, providing a balanced diet, and keeping them in schools, you can enjoy the beauty and liveliness of these charming fish in your tank.
