GloFish are not dyed, they possess a natural fluorescence gene and teir color won't fade. They absorb light and re-emit it which creates the impression that they are glowing. GloFish were developed by adding a natural fluorescence gene to a zebra danio egg. The offspring incorporated the gene and continued to pass it down to its own offspring. GloFish are hardy, community fish that get along well with other fish species, but be careful when combining other fish with GloFish, as not all fish are friendly.
