Black Skirt Tetra – Gymnocorymbus Ternetzi


Common name: Black Skirt Tetra

Scientific name: Gymnocorymbus Ternetzi

Average Adult Fish Size:  2 inches  /  6 cm

Place of Origin: South America.

Typical Tank setup: Well planted with rocks and driftwood/bogwood. They love playing in a moderate to strong current.

Recommended Minimum Aquarium Capacity: 20 gallon / 80 litre

Compatibility: It is very common to find tetras with Corydoras as companions, as they are both quite peaceful and other tank mates like Guppies, other Tetras, Rasboras, Mollies & Platies.

Temperature: 75 – 80 Deg F / 24 – 27 Deg C

Water chemistry: pH 6.0 – 7.5

Feeding: Black Skirt Tetra will accept almost anything put in the tank so a stable diet of normal tropical flakes is the best place to start.

Sexing: The female will usually be larger and the male may have a wider anal fin.

Breeding: Dimly lit tank with some fine leaved plants on the bottom to catch the eggs will encourage breeding. Be sure to remove parents after they have spawned to avoid them eating the eggs.

Additional Information: This tetra is generally peaceful but they are sometimes prone to fin nipping on some of their tank mates. Keeping them in a school of 6 or more may help alleviate this problem.
