• • The Bleeding Heart Tetra (Hyphessobrycon erythrostigma) is a striking freshwater species named for the vivid, heart-shaped red mark on its body. This unique feature, combined with shimmering silver scales and graceful fins, makes it a popular choice among aquarists.

  • Native to slow-moving rivers and streams of South America, particularly in the Upper Amazon Basin, Bleeding Heart Tetras thrive in well-planted aquariums that mimic their natural habitat.

• Appearance & Behavior:

  • Easily recognized by the distinctive red “heart” spot located just behind the gill plate.

  • Males typically display elongated dorsal fins with a flowing, black-tipped edge, while females are slightly rounder with shorter fins.

  • Peaceful in nature, but best kept in groups of at least 6–8 individuals to reduce stress and encourage natural schooling behavior.

  • Their gentle temperament makes them excellent candidates for community aquariums.

• Water Conditions:

  • Temperature: 72–80°F (22–27°C)

  • pH: 6.0–7.5 (slightly acidic to neutral)

  • Hardness: 2–15 dGH

  • Bleeding Heart Tetras prefer soft, tannin-rich water similar to Amazonian streams. Adding driftwood and dried leaves can help recreate these conditions while providing a natural look.

  • A gentle water flow with plenty of live plants and hiding spots creates a stress-free environment.

• Tank Setup:

  • Minimum tank size: 30 gallons (to allow free swimming space for schools).

  • Substrate: Fine sand or smooth gravel enhances their natural display.

  • Plants: Amazon sword plants, Java fern, and floating plants provide cover and a natural environment.

  • Lighting: Moderate lighting with shaded areas helps replicate their natural dimly lit waters.

• Tank Mates:

  • Excellent for peaceful community setups.

  • Compatible with other non-aggressive species such as:

    • Neon Tetras, Cardinal Tetras, Rummy Nose Tetras

    • Corydoras Catfish

    • Dwarf Gouramis

    • Peaceful Rasboras and Livebearers

  • Avoid housing with large or aggressive fish like cichlids that may bully or eat them.

• Feeding Habits:

  • Naturally omnivorous and not picky eaters.

  • Ideal diet includes a mix of high-quality flake food, micro pellets, frozen or live foods such as daphnia, brine shrimp, and bloodworms.

  • Supplement with occasional vegetable-based flakes or blanched vegetables for balanced nutrition.

  • Feed small amounts 2–3 times daily, ensuring they consume all food within a few minutes to avoid water pollution.

• Care Level:

  • Rated as easy to moderate to care for, making them suitable for beginner and intermediate aquarists.

  • Regular water changes (25–30% weekly) are crucial to maintain water quality.

  • Stable water conditions are essential—sudden shifts in pH or temperature can stress the fish.

  • Monitor schooling behavior: a healthy group will actively swim together, showing vibrant coloration.

• Breeding Information:

  • Breeding in captivity is possible but requires a separate breeding tank with slightly acidic, soft water.

  • Females scatter eggs among plants, and males fertilize them externally.

  • Eggs typically hatch in 1–2 days, but adults may eat the eggs, so separating them after spawning is recommended.

• Why Choose the Bleeding Heart Tetra:

  • Adds eye-catching beauty with its distinctive red heart-shaped mark.

  • Peaceful schooling behavior creates dynamic movement in aquariums.

  • Adaptable to community tanks, blending well with other friendly fish.

  • A hardy species with relatively simple care requirements compared to other tropical fish.

✨ The Bleeding Heart Tetra is more than just a pretty fish—it’s a symbol of vibrancy and harmony for any freshwater aquarium. With the right care, these tetras can live up to 5 years, providing long-lasting beauty and peaceful companionship to your aquatic community.
