GloFish® are among the first genetically engineered animals to be commercialized. Not the first, however, as there was another fluorescent fish made by a different company that sold like hotcakes in Taiwan back in 2003. Over 100,000 bright green medaka fish sold in less than a month, proving that there was quite a market for these . As the GloFish® began selling and upgrading their colors here in the U.S., naturally, the Center for Food Safety sued to stop it. In 2005, their lawsuit was dismissed. California banned the fish with a law intended to stop genetically engineered salmon, later relented, and then turned around and informed the company that they would have to complete an expensive environmental review on top of previous evaluations. The company decided it wasn’t worth the cost, so they are available everywhere else in the U.S. except California.
Shortly thereafter, his team developed a line of red fluorescent zebra fish by adding a gene from a sea coral, and orange-yellow fluorescent zebra fish, by adding a variant of the jellyfish gene.

Commercialization of GloFish sparked legal action to force the FDA to exert regulatory oversight and block further sales. On January 14, the Center for Technology Assessment (CTA) and Center for Food Safety (CFS) filed a lawsuit in the Federal District Court in Washington, D.C. challenging FDA's implementation of the Federal Food, Drug, and Cosmetics Act (FFDCA), National Environmental Policy Act (NEPA), and Administrative Procedures Act regarding procedures by which FDA allowed commercialization of GloFish5. CTA and CFS allege that FDA inaction poses harm to the enjoyment of natural waters, harm to carnivorous fishes, increased exposure to antibiotic-resistant bacteria and viruses due to elements in the expression vector used to produce GloFish, and aesthetic injury from viewing genetically engineered GloFish in aquaria. CTA and CFS asked the court to declare that FDA has regulatory authority under FFDCA, "absence of a clear risk to public health" is not the appropriate regulatory standard, and FDA action was not compliant with NEPA, and to enjoin FDA from allowing further sales of GloFish. The lawsuit is currently pending.Glofish/glo danios.

Thecreators of glofish state that they don't pose an ecological threat because glowfish, like regularzebra danios, won't survive in the wild because they are tropical fish and need a water temperatureof about 24-26 °C (75-79 °F). It's been five years now and so far there doesn't seem to bea problem. Although some people do question the ethics of selling genetically altered fish tothe public just because they are prettier than the original fish.
