White Skirt Tetra - Gymnocorymbus ternetzi

1 Review


The Black Skirt Tetra and White Skirt Tetra are two very different color variations of the same species, Gymnocorymbus ternetzi. The Black Skirt Tetra is the "natural" form and has two black bars on its sides and fades from silver in the front to black towards the rear. The White Skirt Tetra has the same shape but is solid white in color. This tetra gets relatively large and can become nippy to some small tank mates. Because of this, they should not be kept with very small or timid species.

Many tropical community aquariums are populated with tetras, rasboras and other similar schooling fish. Though these fish are rather small, their pleasant temperaments, the schooling behaviors they exhibit and a vast variety of colors and shapes make them popular in the hobby. They can grow anywhere from a few centimeters to a few inches, and can add movement to a freshwater fish tank. Most of these fish are fairly easy to care for and have similar water chemistry and care requirements.

Tetras are probably the the largest group of fish offered for community aquariums. They can be distinguished from other schooling community fish by the small adipose fin present between the dorsal fin and the tail. Tetras include small species that may stay under one inch in length and are suitable for community aquariums to much larger and more robust species that can grow up to several inches and need more aggressive tankmates.

These fish prefer aquariums with plenty plants and ornamentation to explore, but also need plenty of open space to swim. They can be fed commercial flakes, granules and small pellets as a staple diet, with occasional feedings of meaty frozen or freeze dried treats such as bloodworms, plankton, mysis or brine shrimp. They prefer to be kept in groups of six or more to school and feel secure. Fish not kept in proper schools may be stressed and remain hidden or may become extremely nippy and aggressive.

Nice schooling fish. Not troublesome at all.


I had 6 of these with 6 Black (Widow Tetras) in a 55 gal tank without issues. Both schools enjoyed schooling together.They also enjoyed their individual schools and swimming alone. I had no issues with these fish in a tank with one betta.
<br>They like to swim all over the tank too. I had all these tetras for over three years before I relocated and gave them back to the pet shop where I had originally purchased them.
