Cosmic Tetra (Dyed Gymnocorymbus ternetzi)
Freshwater Artificially Coloured Tetra • Important Welfare Information Below
📋 Important Information About This Product
We want to be completely transparent about this listing. The Cosmic Tetra is a dyed White Skirt Tetra — its colouration is created by injecting artificial dye into the fish, not through genetics or natural breeding.
This is different from GloFish varieties (which carry a stable, inherited fluorescent gene and are not harmed by the process). Fish dyeing, by contrast, is widely regarded across the aquarium hobby and veterinary sources as a painful, stressful process that typically shortens the fish's lifespan, and the artificial colour usually fades over time regardless.
We believe you deserve this information before deciding whether to purchase. If you're drawn to a vividly coloured tetra, our GloFish Tetra range offers genuinely safe, stable, genetically-based fluorescent colour as an alternative — please feel free to ask our team about it.
