The first challenge was to insert the genes for fluorescence and then to make that fluorescence a permanent characteristic. The original goal was to develop a species that could identify toxins in the water, making it easier to identify polluted waterways. Scientists in Singapore were among the first to genetically modify fish with fluorescent color. For example, vampire squids native to the deep sea regions excrete a glowing mucus designed to startle predators and hatchet fish are able to adjust the reflections off their bodies with the help of light-producing organs.īioluminescence has been the subject of scientific study for decades and fluorescent genes have been adapted as biomarkers for a wide variety of applications. Bioluminescence is what makes fireflies light up the night sky and it can be seen in a wide variety of underwater creatures. Though GloFish look unnatural compared to most aquarium fish, the characteristic that makes them glow is actually very natural – it’s called bioluminescence. Of course, each color has its own branded name: GloFish can be found in all colors of the rainbow including red, orange, green, blue, pink, and purple.
These are simply aquarium fish (freshwater species) that have inherited a brilliant fluorescent coloration. If you’ve never seen GloFish before, the name alone is enough to conjure up an accurate image.
#TETRA GLOFISH HOW TO#
Read on to learn more about these amazing fish and how to care for them. If you’ve been looking for the perfect way to add some intrigue to your tank, GloFish might just be the solution.
They actually inherit their color genetically from their parents, though there is certainly some human intervention involved. Contrary to common misconceptions, they are not injected with dye or artificially colored. They’re nothing more than common species genetically modified for their fluorescent color. They’re called GloFish and there’s a reason they look familiar. You’ve seen them at the pet store – those fluorescent-colored fish that look strikingly familiar.
