The Glowlight Tetra originates in the Essequibo basin in Guyana. They have been found in the Potaro, Rio Essequibo, and Mazaruni Rivers in South America.
They inhabit forested areas, in small tributaries off the main river channel where the water is usually stained a dark brown colour with tannins from decaying Organic matter and is often soft and highly acidic because of this.
The Glowlight Tetra will eat a variety of foods. It's essential to feed them small-sized food and to vary their diet.
They readily accept good quality crushed flakes, micro pellets and freeze-dried food. They also enjoy live and frozen fare such as brine shrimp and mosquito larvae. These Tetras will not eat any food that falls to the bottom of the tank so try not to overfeed them.
