The Glowlight Tetra is a shoaling fish that should be kept with at least four other members of its own species. Keeping an even larger shoal is recommended since this will make the Glowlight tetras feel much safer in the aquarium. They will also be more active and exhibit a much broader range of natural behaviors.
It is common for this species to form smaller groups when there is a predator (or perceived predator) in the aquarium, and then proceed to swim more freely when they feel safe again. Glowlight tetras are mid-dwellers in the aquarium and will usually stay a few centimeters above the bottom. During feeding, they will quickly swim to the top of the water column since they are happy eaters. If you take good care of your Glowlight tetra, it can live for up to 2-4 years in captivity. The Glowlight tetras are peaceful and can be combined with other non-aggressive species of roughly the same size in a community aquarium
