Hemigrammus Erythozonus, or Glowlight Tetra,  also known in some references as Hemigrammus Gracilis.  This well known and popular community and planted tank fish is colorful, yet in my experience, rather shy and many times hidden from view.  In my tank, this may in part be due to the fact that I kept these fish with Angel fish, and Angel fish as they mature harass smaller fish like the Glowlight Tetra. This fish originates from the Guianns and adjacent regions of the Amazon, in shady jungle rivulets and swamps.  They  will grow to be 1.5 to 2 inches in length, though usually in captivity they do not achieve a full 2 inches.  Their body shape and demeanor are similar to those of the Cardinal Tetra.  Their coloration is striking, with a shimmering gold stripe passing through their  otherwise nearly transparent body. They prefer soft, slightly acid water, will eat flake food, brine shrimp and blood worms, and will thrive in water temperatures between 75 and 82 degrees Fahrenheit.
