• Use a fine, dark substrate to mimic their natural habitat.
• Incorporate plenty of live plants, driftwood, and hiding spots.
• Maintain soft, slightly acidic water with consistent parameters.
• Provide subdued lighting to enhance their translucent body and red tail.

Regular water changes and moderate filtration will help ensure their long-term health.

Diet and Feeding

Glass Bloodfin Tetras are omnivores and thrive on a varied diet. Offer:

• High-quality flake or pellet food as a staple.
• Frozen or live foods such as brine shrimp, bloodworms, and daphnia.
• Vegetable matter like finely chopped spinach or blanched zucchini for added nutrition.

Feed small amounts 2–3 times a day, ensuring all food is consumed within a few minutes.

Gender Differences

Males are generally slimmer and more streamlined, while females have a slightly rounder belly, particularly when ready to spawn. The differences are subtle but noticeable with close observation.

Breeding

Breeding Glass Bloodfin Tetras is achievable in captivity with appropriate conditions:

• Set up a separate breeding tank with soft, slightly acidic water.
• Include fine-leaved plants or a spawning mop for egg deposition.
• Condition breeding pairs with high-quality live foods.
• Remove adults after spawning to protect the eggs.

Eggs typically hatch in 24–36 hours, and the fry become free-swimming within a few days. Start feeding fry with infusoria or powdered fry food before transitioning to baby brine shrimp.
