The Glowlight Tetra is an ideal fish for beginning aquarists, as it is very hardy and low-maintenance. It is renowned for its signature bright neon red stripe, which runs from the nose to the tail, making it stand out from other fish in the aquarium. This fish originates from the clear water streams of South America and is a great addition to any soft water community aquarium. Furthermore, it is highly compatible with other fish and is an excellent choice for any beginner looking to start their own aquarium.

Glowlight Tetras are an excellent choice for a planted aquarium, as they are eye-catching, hardy, schooling fish. The addition of rocks and driftwood will provide a natural habitat for the fish, while the plants give them places to hide and play. To ensure their health and happiness, water parameters should remain consistent, as they prefer slightly acidic water. Keeping them in odd numbers, five or more, will also encourage the school to interact and be interesting to watch. Furthermore, Glowlight Tetras are easy to care for and can easily make a great addition to any aquarium.

To breed glow-in-the-dark Tetras, separate a pair into a “breeder tank” with no lighting at first, and then gradually increase it until spawning occurs. Water hardness should be less than 4 dKH and live food such as mosquito larvae are great inducers. Be sure to remove the adults after the eggs have been laid, as they will eat them. The eggs should hatch within 30 hours.
