Scientific name: Gymnocorymbus ternetzi
Growing to approximately two inches in length, the Black Tetra can be kept in small groups but looks best in a large shoal. Adults are not as black in coloration as younger fish and are more prone to act aggressively toward smaller tankmates. The water temperature should be in the range of 72º to 82º Fahrenheit with a pH between 5.8 and 8.2 and soft to moderately hard water. The Black Tetra eats all flake and freeze-dried foods.
The natural habitat of the Black Tetra is calm South American waters with overhanging vegetation that blocks sunlight. It feeds near the surface waters, largely on insects that fall on the water's surface.
