Girly With a glowing orange stripe across the center of its body, the Glowlight Tetra is a beautiful fish!Glowlight Tetra Contents A school of these attractive fish will catch the eye of even the most seasoned aquariast. As they get older, the stripe on the Glowlight Tetra becomes more and more pronounced. They just get more and more beautiful. The Glowlight Tetra is a schooling fish and is one of the most peaceful tetras. They are most comfortable in an aquarium with floating plants as well as some open spaces to swim in. Like all fish, they do not over eat, but the Glowlight Tetra does like to eat a small amount of food several times a day. It is best to feed them what they will eat in about three minutes, three or four times a day. For more Information on keeping this fish see: |

Habitat: Distribution / Background
The Glowlight Tetra was described by Durbin in 1909. They are found in South America in the Essequibo River of Guyana and they feed on worms, small crustaceans and plants.

- Social Grouping: Groups - Best kept in schools of 5 or more fish.
- IUCN Red List: NE - Not Evaluated or not listed
The Glowlight Tetra is a small more slim-bodied species of tetra. It is similar in appearance to the Black Neon Tetra with its horizontal stripe that seems to glow, but is a distinctly different fish. They can readily be identified, as their body is transparent. As they get older, the stripe becomes more and more pronounced.

- Aquarium Hardiness: Very Hardy
- Aquarist Experience Level: Beginner
Since they are omnivorous the Glowlight Tetra will generally eat all kinds of live, fresh, and flake foods. To keep a good balance give them a high quality flake food everyday. Feed brine shrimp (either live or frozen) or blood worms as a treat.

The Glowlight Tetra are egg layers. When they spawn they lock fins, then while clasped they perform a type of roll-over process in the vegetation. Thus the female releases about a dozen eggs at a time and the male fertilizes them.
Because of this spawning behavior, the Glowlight Tetra is one tetra that must not have too dense a spawning vegetation! See the description of how Characins breed in Breeding Freshwater Fish.
- Ease of Propagation: Easy
Neon Tetra Disease
- The Glowlight Tetra has been known to develop ' Neon Tetra Disease'.
- This has been identified as a microscopic sporozoan in the genus Plistophora.
- It shows up on the fish as a spreading spot or blemish beneath the dorsal fin.
- There have been attempts to cure this disease with the use of Methylene Blue, but it is not always successful, so the disease is considered uncurable.
- This disease has also been spotted on the Neon Tetra Paracheirodon innesi, and the Rosey Tetra Hemigrammus erythrozonus.
The Glowlight Tetra is readily available.
