Purple Tetra (Hyphessobrycon metae)

Purple Tetra (Hyphessobrycon metae), also known as the Metae Tetra, is a small, peaceful freshwater fish that is popular in the aquarium hobby. Here are some details about their care requirements:

1. Temperature: Purple Tetras are native to the Orinoco and Meta River basins in South America, where the water is typically warm. To keep them healthy and active, maintain a water temperature between 75°F and 82°F (24°C to 28°C). A heater may be necessary to maintain a stable temperature, especially in cooler climates.

2. Minimum Tank Size: A minimum tank size of 10 gallons (38 liters) is recommended for a small group of Purple Tetras. However, it's always best to provide a larger tank if possible, as a larger space allows for more natural behavior and easier maintenance. These fish are relatively small, growing to around 1.5 to 2 inches (3.8 to 5 cm) in length.

In terms of tank setup and water conditions, here are some additional details:

• Water Parameters: Purple Tetras prefer slightly acidic to neutral water conditions. Aim for a pH level of 6.0 to 7.0 and water hardness (dH) between 4 and 10 dH.

• Filtration: Adequate filtration is crucial to maintain water quality and provide good oxygen exchange. Use a gentle filter to avoid strong currents, as these fish come from slow-moving waters.

• Substrate and Decor: Provide a substrate like sand or fine gravel and include live plants to create hiding places and mimic their natural environment. Driftwood and rocks can also be used for decoration.

• Tank Mates: Purple Tetras are peaceful and do well in a community tank with other non-aggressive fish of similar size and temperament. Avoid keeping them with aggressive or fin-nipping species.

• Feeding: Purple Tetras are omnivorous and will accept a variety of foods. Offer them a balanced diet of high-quality flake foods, pellets, frozen or live foods like brine shrimp and bloodworms.

• Lighting: Moderate to low lighting is generally suitable, and it helps to replicate their natural habitat.

• Water Changes: Regular water changes are essential to maintain good water quality. A 20-30% water change every 2-4 weeks is a good starting point but adjust based on your tank's specific needs.

As with any aquarium fish, it's essential to monitor water parameters, observe their behavior, and adjust care accordingly to ensure the health and well-being of your Purple Tetras.
