Diet
The Bleeding Heart Tetra is an omnivore and benefits from a varied diet.
- Staple Foods:
- High-quality flake food or micro pellets suitable for small fish.
- Live/Frozen Foods:
- Offer daphnia, bloodworms, and brine shrimp for added protein and variety.
- Vegetable Matter:
- Occasionally provide finely chopped blanched spinach or zucchini.
- Feeding Frequency:
- Feed 1–2 times daily, providing only what they can consume within 2–3 minutes.
Behavior and Compatibility
- Temperament:
- Peaceful and social, best kept in schools of 6 or more to reduce stress and encourage natural behaviors.
- Tankmates:
- Ideal companions include other peaceful species, such as:
- Tetras (e.g., Neon Tetras, Rummynose Tetras)
- Corydoras catfish
- Small rasboras or danios
- Avoid aggressive or overly large fish that may intimidate or harm them.

Breeding
Breeding the Bleeding Heart Tetra is possible with the right conditions.
- Sexing:
- Males: Slightly slimmer with longer dorsal fins.
- Females: Rounder and fuller-bodied, especially when carrying eggs.
- Breeding Tank:
- Use a 10–15 gallon tank with soft, acidic water (pH 6.0–6.5) and a temperature of 78°F–80°F (25°C–27°C).
- Provide fine-leaved plants or a spawning mop for egg deposition.
- Spawning:
- Condition the pair with high-quality live/frozen foods.
- Females scatter eggs, which the male fertilizes.
- Egg Care:
- Remove adults after spawning, as they may eat the eggs.
- Eggs hatch within 24–36 hours, and fry become free-swimming after 3–5 days.
- Fry Care:
- Feed fry with infusoria or finely powdered fry food initially, transitioning to baby brine shrimp as they grow.
Common Challenges
- Schooling Needs:
- Keep them in groups to prevent stress and promote natural behavior.
- Water Sensitivity:
- Sensitive to poor water quality; regular maintenance is essential.
- Tankmates:
- Avoid aggressive or predatory fish that may outcompete or harm them.
