Mexican Tetra

The Mexican Tetra, Astyanax mexicanus, is a freshwater species of characin native to Central America, particularly found in Mexico. It can grow up to 12 cm (4.7 inches) in length and has a silver-gray body with a dark horizontal stripe. This species is known for its adaptability to different water conditions and can be kept in community tanks.

Mexican Tetras are omnivorous and will eat a variety of foods, including flake and pellet foods, as well as live or frozen foods like bloodworms, brine shrimp, and daphnia. Providing a varied diet will help keep them healthy and vibrant.

Males tend to have more coloration and a slimmer body, while females are larger and rounder.

Mexican Tetras are egg layers and can be bred in a separate breeding tank. A ratio of one male to two females is recommended for breeding. The breeding tank should have a soft substrate and plants for the female to lay her eggs on. The eggs will hatch in 24-36 hours, and the fry can be fed infusoria or liquid fry food.

Mexican Tetras can be susceptible to common freshwater diseases like ich and fin rot. It's essential to maintain good water quality and provide a balanced diet to prevent illness.

Mexican Tetras are native to Central America, particularly found in Mexico.

Mexican Tetras are generally peaceful and can be kept in community tanks, but they may nip at the fins of other fish. They may also be prone to jumping out of the aquarium, so a tightly fitting lid is recommended.

When introducing Mexican Tetras to a new aquarium, it's essential to acclimate them slowly to prevent shock. Float the bag in the aquarium for 10-15 minutes to equalize the temperature, then slowly add small amounts of aquarium water to the bag over a period of 30-45 minutes before releasing them into the tank.
