Ever wondered where GloFish® fluorescent fish come from? Have questions about taking care of your GloFish? Curious about how aquariums work? Keep reading!
Where do GloFish come from? Each color of GloFish was developed by adding a gene into a fish embryo to make it a fluorescent color (red, green, orange, blue, purple, or pink). The fish then grew up and passed the fluorescent color to its offspring. Because of this, each color of GloFish has the same ‘ancestor’ GloFish. For example, all of the Starfire Red® GloFish Danios come from a single red fluorescent danio.
Where does the fluorescent color come from? The fluorescence in GloFish is derived from fluorescent protein genes that naturally occur in marine organisms.
What does it mean that GloFish are ‘fluorescent’? This means that GloFish absorb light, then “send it back out.”
In what colors are GloFish fluorescent fish available? GloFish come in six colors: Starfire Red®, Electric Green®, Sunburst Orange®, Cosmic Blue®, Galactic Purple®, and Moonrise Pink™.
Do GloFish actually glow? GloFish absorb light and then send it back out. However, they do not actually glow.
Does the fluorescence harm the fish? No. GloFish are as healthy as their non-fluorescent counterparts, just much brighter!
How do GloFish help fight against pollution? GloFish were originally bred to help detect pollution in water. Scientists have recently developed fluorescent fish that fluoresce only when they detect pollution.
