The bleeding heart tetra, also known as the red minor tetra, is a popular freshwater fish species among aquarium enthusiasts. It is named after the striking red spot on its body that resembles a bleeding heart. These tetras are native to South America, particularly the Amazon River basin.

In terms of appearance, bleeding heart tetras have a silver body with a black horizontal stripe that runs from the middle of their body to the tail fin. The most distinctive feature is the vibrant red patch on their sides, which gives them their name. This red spot is more prominent in males and can vary in size and intensity depending on their mood and health.

Bleeding heart tetras are peaceful and social fish that thrive in shoals. It is best to keep them in groups of at least six individuals to ensure their well-being and reduce stress. They are relatively small, reaching about 2 inches (5 cm) in length, making them suitable for smaller aquariums.

These tetras prefer well-planted aquariums with a lot of swimming space. They appreciate a soft, slightly acidic water environment, so it's important to maintain suitable water parameters. They are omnivores and will eat a variety of foods, including high-quality flakes, pellets, and small live or frozen foods like brine shrimp or bloodworms.

When it comes to tank mates, bleeding heart tetras are generally peaceful and can coexist with other peaceful fish of similar size. However, avoid keeping them with aggressive or fin-nipping species, as their flowing fins make them vulnerable to such behavior.

Overall, bleeding heart tetras are a beautiful and captivating addition to any community aquarium. With proper care and suitable tank conditions, they can display their vibrant colors and bring life to your aquatic setup.
