Glowlight Tetra

Hemigrammus erythrozonus.
Glow light tetras are happiest and show off their colors best in a tank with subdued lighting and a dark substrate. The water should have a pH of 6.5 and the temperature maintained between 25-27'C. The tank should be medium sized ( 70 liter ) and decorated with live plants and some driftwood. Stock the aquarium with equally peaceful species and keep them in as large a shoal as possible. Once established they are easily fed and cared for with flake and frozen food.
Overall a very pleasing species to look at. The anal, ventral and dorsal fins are slightly off white to translucent in coloration, in addition the front of the dorsal fin is marked by a bright red stripe. This color is repeated on the top section of the eye. The basic body color is pale translucent olive green color. There is a shimmering purple to red stripe starting at the base of the tail fin extending to the mouth area.
They grow up to 5 cm.
