The cardinal tetra has a brilliant neon blue stripe running from the nose to the tail. Below this blue stripe is a brilliant red stripe. The vivid red coloration bleeds into the tail, which is otherwise transparent, as are the other fins. The underbelly is a soft white, setting off this beautifully colored fish.
Cardinal tetras, like other tetra species, are a peaceful, social fish that should be kept in schools. Schools should be large, with a minimum size of a half-dozen fish. They are suitable for community tanks as long as water conditions are favorable and other species are peaceful.
Much like the neon tetra, this species requires a mature tank that has soft acidic water. More importantly, water chemistry should be stable. This is not a species that does well in a newly started aquarium.
The ideal pH is below 6, and the hardness should not be above 4 dGH. Subjecting this species to water that has a high mineral content is a recipe for poor health and shortened lifespans. The water temperature can encompass a broader range, from 73 to 81 degrees F (23 to 27 degrees C).
