Glo Starfire Red Tetra (Gymnocorymbus ternetzi var.) for Sale in Canada
The Glo Starfire Red Tetra (Gymnocorymbus ternetzi var.) is a striking freshwater aquarium fish admired for its brilliant fluorescent red coloration and active schooling behaviour. Based on the familiar Black Skirt Tetra, this colourful variety brings intense visual impact to a well-maintained community aquarium.
A healthy group of Starfire Red Glo Tetras creates an energetic display as the fish move through the middle areas of the aquarium. Their vivid red appearance contrasts beautifully with green aquatic plants, dark substrate, natural driftwood, and darker aquarium backgrounds.
These fish are social and active, making them best suited to a properly sized aquarium with compatible tank mates. Keeping them in a suitable group helps encourage natural social behaviour and can reduce stress.
