This fish is found naturally in South America. The adult fish attain a length of 2 inch.
The main body colouring is silvery with a clearly defined black line running horizontally along the middle of the body.
The main attraction of this species is the reality that they’re prolific, easy-to-breed Characins which are well suited as a beginner’s fish. The eggs, which are deposited on fine-leafed plants, are adhesive. The regular temperature range is between 65° – 80° F, but this should be adjusted to about 78° F for breeding purposes.
Black-line tetras are poor fish to put indiscriminately into a community tank, as they’ve a tendency to chase other fish and devour any little sufficient to be eaten.
