The Glowlight Tetra is a really nice looking tetra with an orange-red stripe that runs the length of its semi-transparent body. Proper aquarium lighting levels with a dark fish tank bottom can help enhance the colors of these tetras. They are slightly smaller than other commonly available tetras and should be kept with similar sized and non-aggressive species. They will do really well in an aquarium with live plants. Like other small tetras, such as the Neon Tetras, this fish does best in small schools (shoal) of 5 or more. Do not keep them with larger species that could potentially eat them. Even if you keep them in schools they can still be a little shy, keeping a low profile most of the time.
These tetras are readily available and are usually very inexpensive. There is a golden glowlight and albino variety being offered for sale too.
It's always a good idea to keep your new Glowlight Tetras in a quarantine tank for a few weeks for monitoring before introducing them into your main tank. Many of the Glow-light tetras available are now being farm raised but this fish can still be sensitive to fluctuations in pH and temperature. You may want to take a little longer when acclimating them to your tank water. Take an hour (instead of 15 minutes) and slowly add small amounts of tank water to the bag every 10 minutes or so.
They will accept smaller fish food including flakes, frozen, freeze dried and live foods (crickets and worms). They may also eat smaller top dwelling fish.

I have owned Glowlight tetras since I began keeping an aquarium. I have found that they are fairly easy fish to care for. They make excellent beginner fish. The only real problem you may have with them is larger fish picking on them, like nipping their fins and such. But overall, a very peaceful fish and get on great with Neon Tetras and fish of similar size.

One of the larger tetras reaching up to 16 inches (42 cm) in size as adults.
Only gets to about an inch in size so it's one of the smaller tetras.
Has some nice colors and looks really good in a planted aquarium.
