The Cardinal Tetra is a good, schooling community fish that gets along with everyone. The bigger the school, the better its coloration becomes. They should always be kept in a group of 5 or more individuals, with larger groups of at least 10 or more being best.
Keep in mind that it will be eaten by most any fish that can fit it in its mouth, so choose tankmates carefully. The Cardinal Tetra is the natural prey of many fish, even of many other tetras. it does best with other small tetras, pencil fish, hatchet fish, dwarf cichlids, small Loricariids, small rasboras, and anabantoids.The Cardinal Tetra has been bred in captivity, but breeding them successfully in home aquariums can be very tricky. An aquarist who wants to attempt breeding them must be sure to have optimal water conditions and compatible pairs. These fish require highly specific water conditions that match those of its natural habitat. Obtaining compatible breeding pairs is not always easy either. However, given the right conditions, these fish will spawn in a community tank. Unfortunately, the eggs and fry will most often be eaten. A separate breeding tank is best.
