Several species have been modified, including Zebra Danio , Skirt Tetra , Tiger Barb , Corydoras , Betta , Rainbow Shark , and Angelfish .

A common misconception is that they are injected with dye; true GloFish are produced via safe, genetic engineering. Glowfish

GloFish are a popular brand of genetically engineered freshwater aquarium fish known for their vibrant, fluorescent colors. They are not injected with dye; rather, they inherit their glow from parents modified with genes from marine organisms like jellyfish and coral. 1.

While legal in most places, they are restricted in certain areas (e.g., California), due to regulations against introducing transgenic species into the wild.

Originally, these fish were developed by researchers in Singapore (later patented in Texas) to detect toxins in water, with the intent that they would glow differently in polluted water.

Most GloFish species (like Tetras and Danios) are hardy and maintain the same, often peaceful, behavioral traits as their non-fluorescent counterparts.
