The red eye tetra (Bario sanctaefilomenae, formerly Moenkhausia sanctaefilomenae) is a hardy, energetic freshwater schooling fish native to the river basins of South America. It is widely celebrated in the aquarium hobby for its shimmering appearance and distinct, bright red eyes.
Physical Characteristics
- Appearance: They feature a bright, metallic silver body with large, broad scales. The upper portion of the iris is marked by a vibrant, signature red ring.
- Tail Markings: The base of the tail fin (caudal peduncle) has a prominent black band bordered by a bright white or yellowish stripe.
- Size: They grow to an adult size of roughly 6 to 7 cm (2.5 to 3 inches).
- Body Shape: They have a relatively deep, compressed, and streamlined profile.
- Lifespan: They typically live for 3 to 5 years in a well-maintained environment.
Temperament & Behaviour
- Schooling Nature: They are strict schooling fish that must be kept in groups. While groups of 6 are standard, larger shoals of 10 to 12+ promote better color and overall security.
- Activity Level: They are very active, fast-swimming mid-water dwellers that occupy the top two-thirds of the aquarium.
- Nipping Tendencies: Though generally peaceful community fish, they can become fin-nippers if kept in isolation or in groups that are too small.
Aquarium Care Summary
- Tank Size: Minimum of 100–110 litres (approx. 20–30 gallons) to support their active swimming needs.
- Water Parameters: Temperature: 22–28°C (72–82°F) | pH: 6.0–8.0 | Hardness: Up to 20 dGH.
- Diet: Omnivorous and highly unpicky; they readily consume premium flakes, pellets, frozen, and live foods.
