Petco, in recent months, has really been pushing sales for GloFish. They are tetras, danios, and sharks that have been genetically altered in embryo to produce brightly colored, neon florescent fish. Or…. so they claim. It’s what I had believed, but today I got a good look at a GloFish that had died and been returned. The owner had frozen the fish but it had thawed by the time they returned to the store, and the water that it had produced was the exact shade of bright neon pink as the fish.
Petco GloFish are dyed. Thats the only explanation. If they were really genetically altered the water would not have been the same color as the fish. Dying or injecting fish is extremely cruel and harmful, with a high mortality rate and for survivors a shortened lifespan. This is not a practice that should be supported. So, please don’t buy them.
