The Diamond Head Neon Tetra comes from the clear waters of South America. The Diamond Head variety of Paracheirodon innesi has been developed through selective breeding. This variety has a metallic "diamond" patch on its back between the eyes and dorsal fin. It can be identified by the bright blue stripe, offset by red, that runs horizontally down the side of its body.
In at least a 10-gallon aquarium, plants, rocks, and some driftwood should be used to give the Diamond Head Neon Tetra hiding spaces and security. It is a mid-level swimming fish, so taller plants should be used. The Diamond Head Neon Tetra requires a steady, slightly acidic pH and constant temperature.
In the aquarium, the female will lay a relatively small number of eggs, which hatch in about 24 hours after fertilization. This can happen frequently if large numbers of Diamond Head Neon Tetras are present. To avoid losing the fry, a separate "breeding tank" should be used.
The Diamond Head Neon 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.
