Breeding
Regrettably, comprehensive information on the breeding of Xingu Black Neon Tetras remains scarce due to their rarity. However, drawing from the breeding behaviours of other Moenkhausia species, we can infer some general guidelines. Breeding these Tetras will require the setup of a dedicated breeding tank, providing specific conditions to encourage successful reproduction.
Creating an optimal breeding environment begins with a dimly lit tank, complemented by soft water conditions. Slightly elevating the temperature above their usual range can help stimulate breeding behaviour. Dense planting within the breeding tank is crucial, as it offers essential shaded areas for the Tetras to deposit their eggs.
To ensure the production of healthy offspring, carefully select a robust female and a male with vibrant colours. Then, introduce them to the breeding tank and continue to provide them with a nutrient-rich diet, including live food, to enhance their reproductive readiness.
When Xingu Black Neon Tetras are prepared to breed, they will engage in fin-locking behaviour, followed by a graceful somersaulting movement among the plants. Then, the female will release a batch of approximately a dozen eggs at a time, which the male will swiftly fertilize. Typically, spawning activity occurs during the early morning hours, with the female eventually laying a considerable number of eggs, often reaching several hundred.
To safeguard the developing eggs, it is crucial to promptly remove the parents from the breeding tank. Adult Tetras have a tendency to consume the eggs, which may hinder successful hatching. After approximately 24 to 36 hours, the eggs will start to hatch, and within 3 to 4 days, the fry will become free-swimming, embarking on a rapid growth journey.
The newly hatched fry will initially sustain themselves by consuming their yolk sac. Once the yolk sac has been absorbed, they will eagerly accept infusoria-type foods, progressing to baby brine shrimp and crushed flakes as they continue to develop.
Diet & Feeding
Xingu Black Neon Tetras demonstrate a versatile and accommodating appetite within the confines of the home aquarium. While they readily accept a variety of food offerings, a diverse and well-rounded diet is essential to showcase their vibrant colours and ensure optimal health. This should encompass a combination of high-quality dried foods, such as flakes and granules, alongside regular servings of live, frozen, or freeze-dried delicacies. Mosquito larvae, daphnia, Moina, and brine shrimp are excellent choices to incorporate into their feeding regimen.
To promote a balanced nutritional intake, it is advisable to feed Xingu Black Neon Tetras multiple times a day, providing them with an amount of food that can be consumed within three minutes or less. This feeding approach optimizes their feeding response and helps maintain water quality within the aquarium. Furthermore, by curating a varied and enticing menu for these captivating Tetras, aquarists can revel in the spectacle of their enhanced colours and the vitality that accompanies a well-nourished aquatic companion.
