Blackline Tail Tetra

Blackline Tail Tetra (Moenkhausia costae), also known as Costae Tetra, is a vibrant and active freshwater fish native to the rivers of Brazil. Here are some key points about them:

• Appearance: They have a striking black line that runs along their tail, contrasting beautifully with their silver body and red fins. They grow up to 6 cm (2.4 inches) in length.
• Habitat: They thrive in soft, acidic water with a temperature range of 24-28°C (75-82°F) and a pH range of 6.0-7.5.
• Behavior: These tetras are peaceful and highly sociable, making them excellent for community tanks. They are known for their energetic and playful nature.
• Nature: In the wild, they feed on small insects, larvae, and plant matter. In captivity, they thrive on a varied diet of high-quality flake food, frozen or live brine shrimp, and daphni.
• Tank setup: They prefer a well-planted tank with a dark substrate and background to enhance their colors. A secure lid is recommended as they are known jumper.
• Breeding: Breeding them in captivity requires specific water conditions, mimicking their natural habitat with soft, slightly acidic water. A separate breeding tank is recommended for the best results.
