Care and Environment
Providing optimal care for the Black Skirt Tetra involves attention to tank size, water parameters, and environmental enrichment.
What is the minimum tank size for a Black Skirt Tetra?
A minimum of 60 liters is recommended to accommodate a small group, as they are schooling fish.
What are the ideal water parameters for Black Skirt Tetras?
They thrive in temperatures between 20°C and 28°C, with a pH range of 6.0 to 7.5, and water hardness between 5 to 20 dGH.
Filtration should be efficient to maintain water quality, and lighting can be moderate. A well-planted tank with open swimming areas and hiding spots, such as driftwood and caves, mimics their natural habitat. Feeding should include a variety of high-quality flakes, pellets, and occasional live or frozen foods like brine shrimp or bloodworms.
Do Black Skirt Tetras have any specific care challenges?
