Scientific Name: Prionobrama filigera

Wild Origin: South America, primarily found in the Amazon River Basin
The Glass Bloodfin Tetra is a small, transparent freshwater fish with a striking red tail fin, which gives it its name. Its body is almost completely see-through, allowing you to observe its internal structure, much like the Glass Catfish, though with the addition of its distinctive red fins. This species is popular among aquarists due to its peaceful nature, active schooling behavior, and unique appearance. Glass Bloodfin Tetras typically grow to about 1.5-2 inches (4-5 cm) in length and can live up to 5-8 years in a well-maintained aquarium.
Habitat and Tank Requirements:
Glass Bloodfin Tetras are native to the slow-moving rivers and tributaries of South America. In the home aquarium, they thrive in a setup that mimics their natural habitat, with plenty of swimming space, soft water, and a well-planted environment.
Tank Size and Water Parameters:
| PARAMETER | RECOMMENDED |
|---|---|
| Tank Size | Minimum 40 litres |
| Temperature | 72-80°F (22-27°C) |
| pH | 6.0-7.5 |
| Hardness | Soft to moderately hard water, 2-12 dGH |
Glass Bloodfin Tetras prefer soft, slightly acidic to neutral water. A well-planted tank with floating plants will provide the cover they need to feel secure, while also offering areas for open swimming. The aquarium should have a gentle current, and the water must be kept clean through regular water changes, as these fish are sensitive to poor water conditions.
Low to moderate lighting is recommended to reduce stress, and floating plants can help create shaded areas, which Glass Bloodfin Tetras prefer. A sandy or fine gravel substrate is ideal for this species, along with plants like Java fern, Anubias, or Amazon swords.
We Recommend:
These carefully selected options provide a well-balanced nutritional profile, ensuring that your fish receive the essential nutrients they need for optimal growth, vibrant colors, and overall health. By offering a variety of these high-quality foods, you can help maintain the vitality and well-being of your fish, promoting a healthy and thriving aquarium environment.
Behavior and Compatibility:
Glass Bloodfin Tetras are peaceful, schooling fish that do best in groups of 6 or more. Keeping them in small schools allows them to display their natural behaviors and reduces stress. When kept in larger groups, they will swim together in the middle and upper levels of the tank, creating a mesmerizing display.
These tetras are excellent tank mates for other peaceful community fish, such as tetras, rasboras, guppies, Corydoras catfish, and small gouramis. They are non-aggressive and are unlikely to bother other fish, making them an ideal choice for community setups. Avoid housing them with aggressive or larger species, as they may be outcompeted for food or stressed by tank mates.
