Glowlight Tetra - Hemigrammus erythrozonus
Many tropical community aquariums are populated with tetras, rasboras and other similar schooling fish. Though these fish are rather small, their pleasant temperaments, the schooling behaviors they exhibit and a vast variety of colors and shapes make them popular in the hobby. They can grow anywhere from a few centimeters to a few inches, and can add movement to a freshwater fish tank. Most of these fish are fairly easy to care for and have similar water chemistry and care requirements.
Tetras are probably the the largest group of fish offered for community aquariums. They can be distinguished from other schooling community fish by the small adipose fin present between the dorsal fin and the tail. Tetras include small species that may stay under one inch in length and are suitable for community aquariums to much larger and more robust species that can grow up to several inches and need more aggressive tankmates.
These fish prefer aquariums with plenty plants and ornamentation to explore, but also need plenty of open space to swim. They can be fed commercial flakes, granules and small pellets as a staple diet, with occasional feedings of meaty frozen or freeze dried treats such as bloodworms, plankton, mysis or brine shrimp. They prefer to be kept in groups of six or more to school and feel secure. Fish not kept in proper schools may be stressed and remain hidden or may become extremely nippy and aggressive.

Good peaceful tetra.
by Matthew Zito
Good peaceful tetra. Pretty hardy. Good with plants and snails. Colors really pop with a dark background. Mixes well with Neons, Black Neons and Ancistrus (AKA Bristlenose Plecos).
Worthy addition. Schooling fish.
These don't look like much in the store. Take them home and place them in a dark or heavily planted (artificial or live) and see them light things up. I had five for awhile they started dying. Unfortunately, I discovered later that they do best in soft water. My water was hard. Be careful of what water you put them in. A good aquarium book will tell you they like soft, acidic water.

Love these! They are a tetra tank must have! I bought 6 of these after going to That Fish Place and PetSmart to get cardinal tetras. That Fish Place didn't have them, and Petsmart's price was ridiculous. I brought my dad with me back to That Fish Place, because I needed medication, and I decided to see if the cardinals were in.They weren't. Bummer. But my dad saw these and loved them. I had 2 cardinal tetras left from a previous batch, and they've been schooling with the glowlights. Very cute!
