Several species have been modified, including Zebra Danio , Skirt Tetra , Tiger Barb , Corydoras , Betta , Rainbow Shark , and Angelfish .
GloFish are fluorescent, meaning they absorb light and re-emit it, appearing to "glow" intensely under blue LED, actinic, or black lights.
The fluorescent protein genes are integrated into their DNA, ensuring the color is passed on from generation to generation. 2. Varieties and Colors Glowfish
They are not bioluminescent—they will not glow in a completely dark room without a light source.
A common misconception is that they are injected with dye; true GloFish are produced via safe, genetic engineering. Several species have been modified, including Zebra Danio
They come in a "cosmic" range of colors: Starfire Red, Electric Green, Sunburst Orange, Cosmic Blue, Galactic Purple, and Moonrise Pink. 3. Environmental & Scientific Origins
If you're considering setting up a tank,g., Tetra vs. Betta ) is ? What equipment is needed to make them glow? Which fish make good tank mates for them? GloFish Species And the Science Behind Their Glow. They come in a "cosmic" range of colors:
Most GloFish species (like Tetras and Danios) are hardy and maintain the same, often peaceful, behavioral traits as their non-fluorescent counterparts.
