The Diamond Tetra, also known as Brillantsalmler, Diamond Characin, Pittier's Tetra, and Timanttitetra, is native to South American inland waters. It is said to sparkle like a diamond with its silvery scales and orange accents.

The Diamond Tetra prefers a heavily-planted aquarium and softer water on the acidic side. It is an ideal fish to put in a community tank and prefers to school with 8-10 other Diamonds, making them an attractive addition to the home aquarium.

To breed them, separate a pair into a "breeding tank" with no lighting at first, but gradually increase it until spawning occurs. Water hardness should be less than 4 degrees and live food such as mosquito larvae are great inducers. Be sure to remove the adults after the eggs have been laid, as they will eat them. The eggs should hatch within 30 hours.

The Diamond Tetra will accept many small foods such as brine shrimp or daphnia, freeze-dried bloodworms and tubifex, micro pellet food, and a high quality flake food.
