What are GloFish?
GloFish are not just one type of fish but
rather a collection of freshwater species that have been genetically
modified with fluorescent protein genes that naturally occur in
jellyfish, sea anemones, corals, and other marine life. They were
originally developed by scientists to study genetics and help detect
certain pollutants in the water, but their dazzling appearance made them
a popular addition to the aquarium fish industry. These special
fluorescent genes cause the GloFish to vibrantly glow under blue light
and does not appear to impact their quality of life.
