Scientific name: Hemigrammus erythrozonus
A schooling fish, the Glowlight Tetra grows to about two inches and can be kept with other fish of similar size and temperament. Dark tank aquascaping shows off this species at its best. A water temperature in the 74º to 82º Fahrenheit range with a pH of 5.8 to 7.5 and moderately soft to mildly hard water are fine. This fish is not fussy about foods, taking flake and freeze-dried varieties.

The Glowlight Tetra's common name comes from the obvious iridescent red stripe down the fish's side. The stripe also has a faint golden shadow along the top, which stands out in good light. Males are a bit slimmer than females, but the difference is slight and doesn't really serve as a useful way to distinguish between them.
