Overview: The Prionobrama filigera, commonly known as the Glass Bloodfin Tetra, is a striking freshwater fish that adds elegance and vibrancy to any aquarium. Known for its translucent body and vivid red tail fin, this species is a popular choice among aquarists for its peaceful nature and schooling behavior.
Appearance: The Glass Bloodfin Tetra features a semi-transparent body that shimmers under light, allowing glimpses of its internal organs, which contribute to its unique charm. The tail fin is bright red, providing a beautiful contrast to the fish's otherwise subtle coloration. Adult tetras typically grow to about 4-5 cm in length, making them an ideal choice for smaller or community tanks.
Behavior: This species is known for its peaceful demeanor and is best kept in schools of at least six individuals. The Glass Bloodfin Tetra thrives in a well-planted tank, where it can exhibit natural schooling behavior. They are active swimmers, often occupying the mid to upper levels of the aquarium, and their dynamic movement adds life and activity to any aquascape.
Habitat & Care: Glass Bloodfin Tetras are native to the slow-moving waters of South America, particularly in the Amazon River basin. In captivity, they prefer a tank with plenty of plants, subdued lighting, and a gentle water flow. Ideal water conditions include a temperature range of 22-28°C (72-82°F), a pH of 6.0-7.5, and soft to moderately hard water.
Diet: In the wild, these tetras feed on small insects, crustaceans, and plant matter. In an aquarium setting, they readily accept high-quality flake food, micro pellets, and live or frozen foods such as brine shrimp and daphnia. Providing a varied diet will help maintain their vibrant coloration and overall health.
Compatibility: Glass Bloodfin Tetras are highly compatible with other peaceful fish species, making them an excellent choice for community tanks. They can be housed with other tetras, rasboras, small barbs, and even dwarf cichlids. Avoid keeping them with larger or aggressive fish that may view them as prey.
Breeding: Breeding Glass Bloodfin Tetras in captivity can be challenging but rewarding. They are egg scatterers, and a separate breeding tank with fine-leaved plants or a spawning mop is recommended. The water should be slightly acidic and soft. Once the eggs are laid, remove the adults to prevent them from eating the eggs. The fry will hatch in 24-36 hours and should be fed infusoria or finely crushed flake food.
Conclusion: With their delicate appearance and peaceful nature, Prionobrama filigera are an excellent addition to any planted aquarium. Their schooling behavior and compatibility with other species make them a favorite among aquarists looking to create a harmonious and visually appealing underwater landscape.
