The cardinal tetra is a very popular aquarium fish, but is less widespread than the neon tetra because until recently, it was difficult to breed in captivity. However, many breeders are now producing the fish; in most cases, one can determine if the cardinal tetra is bred or wild-caught due to damaged fins on wild-caught specimens.
The fish are also not caught by fish farmers during their breeding season. [9] The cardinal tetra, especially, is considered a renewable resource. [10] Project Piaba assesses the sustainability of the species farmed in the Rio Negro area by using the "F value" which estimates the portion of the catch from the total biomass. [11]

Also, its body is slimmer than that of the neon tetra. It grows to a maximum overall length of about 3.5 cm (1.4 in).
