Their longevity is heavily influenced by the quality of their environment, particularly water conditions within the tank. Neglecting water quality can significantly reduce their lifespan. Regular monitoring and maintenance of water parameters are crucial to ensure their well-being.

Here are some ideal tank mates we recommend for Black Skirt Tetras:

  1. Neon Tetras

What Do They Eat ?

In their natural habitat, Black Skirt Tetras are opportunistic feeders, consuming a wide range of foods including small insects, plants, and whatever else they come across. Similarly, in captivity, they don’t exhibit particular dietary preferences, giving you the flexibility to choose their diet.

A high-quality staple food like Northfin Community Formula is an excellent choice to provide essential nutrients for their overall health. Additionally, commercially available dry and frozen foods rich in nutrients can be included in their diet.

Some enthusiasts opt to incorporate live foods such as bloodworms, brine shrimp, daphnia, and mosquito larvae into their diet. If you choose to feed live foods, ensure they are fresh and free from harmful bacteria and pathogens. Culturing your own live foods is an option for those interested, but frozen varieties are a convenient alternative for many fishkeepers.

For a convenient and nutritious ready-to-feed staple food, consider pellet options like Northfin Community Formula. These pellets are appropriately sized for nano fish like Black Skirt Tetras and are formulated without fillers, providing a well-balanced diet.

Remember, variety is key to a healthy diet. Rotate between different food types to ensure they receive a diverse range of nutrients essential for their well-being.
