In addition to the red zebrafish, Yorktown Technologies released green and orange-yellow versions of the zebrafish in mid-2006. In 2011, blue and purple zebrafish were released. These lines of fish incorporate genes from sea coral.<ref name=gf /> In 2012, Yorktown Technologies introduced a green version of a GloFish derived from a different species of fish, the [[black tetra]].<ref name=gf /> This was followed by a green version of a [[tiger barb]]. In 2013, Yorktown Technologies introduced orange, pink, and purple Tetras, which made Tetras the first GloFish to be available in pink. This was followed in 2014 by the release of red and blue Tetras. The colors are trademarked as "Starfire Red", "Moonrise Pink", "Sunburst Orange", "Electric Green", "Cosmic Blue", and "Galactic Purple".

Other fish released include the GloFish shark, available in orange, green, and purple. Though these fish are not scientifically related to sharks, they are based on the albino rainbow shark.<ref>{{Cite press release|url=https://www.prnewswire.com/news-releases/spectrum-brands-pet-llc-introduces-glofish-sharks-to-glofish-family-of-fluorescent-fish-300582584.html|title=Spectrum Brands Pet LLC Introduces GloFish® Sharks to GloFish® Family of Fluorescent Fish|last=Pet|first=Spectrum Brands|website=www.prnewswire.com|language=en|access-date=2020-02-12|archive-date=2020-02-12|archive-url=https://web.archive.org/web/20200212211938/https://www.prnewswire.com/news-releases/spectrum-brands-pet-llc-introduces-glofish-sharks-to-glofish-family-of-fluorescent-fish-300582584.html|url-status=live}}</ref> In February 2020, green GloFish bettas also known as Globettas were released, with three different variations. These variations include female, (young) male, and premium (adult) male.

Despite the speculation of aquarium enthusiasts that the eggs of the fluorescent fish were pressure treated to make them infertile, it has been found some GloFish are indeed fertile and will reproduce in a captive environment.<ref name="Finformation">{{cite web|url=http://www.gpasi.org/Apr04.pdf |pages=4–5 |title=Finformation |work=Greater Pittsburgh Aquarium Society |url-status=dead |archive-url=https://web.archive.org/web/20081217173629/http://www.gpasi.org/Apr04.pdf |archive-date=2008-12-17 }}</ref> However, the GloFish Fluorescent Fish License states "Intentional breeding and/or any sale, barter, or trade, of any offspring of GloFish fluorescent ornamental fish is strictly prohibited".<ref>{{cite web | title=License Notice | url=https://shop.glofish.com/pages/license-notice | access-date=13 June 2021 | archive-date=13 June 2021 | archive-url=https://web.archive.org/web/20210613141000/https://shop.glofish.com/pages/license-notice | url-status=live }}</ref>

Sale or possession of GloFish was made illegal in [[California]] in 2003 due to a regulation that restricts genetically modified fish. The regulation was implemented before the marketing of GloFish, largely due to concern about a fast-growing biotech salmon. The regulations were lifted in 2015 due to a growing body of evidence and the findings of the Food and Drug Administration and the [[Florida Department of Agriculture and Consumer Services]]. GloFish are now legal in California for importation and commercial sale.<ref>{{cite web | title= Letter from Director Charlton H.

The import, sale and possession of these fish is not permitted within the European Union. On November 9, 2006, however, the Netherlands' Ministry of Housing, Spatial Planning and the Environment (VROM) found 1,400 fluorescent fish, which were sold in various aquarium shops.<ref>[http://www.vrom.nl/pagina.html?id=25069 vrom.nl] {{webarchive |url=https://web.archive.org/web/20070309084310/http://www.vrom.nl/pagina.html?id=25069 |date=March 9, 2007 }}</ref>

In January 2009, the U.S. Food & Drug Administration formalized their recommendations for genetically engineered animals.<ref>{{cite web|url=https://www.fda.gov/cvm/geanimals.htm|title=Genetically Engineered Animals|work=fda.gov|access-date=2019-12-16|archive-date=2009-05-11|archive-url=https://web.archive.org/web/20090511170825/http://www.fda.gov/cvm/GEAnimals.htm|url-status=dead}}</ref> These non-binding recommendations describe the way in which FDA regulates all GM animals, including GloFish.<ref>{{cite web| title=Regulation of Genetically Engineered Animals Containing Heritable Recombinant DNA Constructs| website=[[Food and Drug Administration]]| url=https://www.fda.gov/downloads/AnimalVeterinary/GuidanceComplianceEnforcement/GuidanceforIndustry/UCM113903.pdf| access-date=2019-12-16| archive-date=2019-01-08| archive-url=https://web.archive.org/web/20190108233953/https://www.fda.gov/downloads/animalveterinary/guidancecomplianceenforcement/guidanceforindustry/ucm113903.pdf| url-status=dead}}</ref>

Research published in 2014 assessed the environmental safety associated with GloFish. One paper concluded that there is little risk of [[Genetically modified food controversies#Environment|invasiveness]] into the environment.<ref>{{cite journal| doi=10.1080/00028487.2014.880741| url=http://www.tandfonline.com/eprint/nvuFmCDyamiIZp4qAMeW/full#.U7cfS_ldWQE| title=Assessment of the Risks of Transgenic Fluorescent Ornamental Fishes to the United States Using the Fish Invasiveness Screening Kit (FISK)| journal=Transactions of the American Fisheries Society| volume=143| issue=3| pages=817–829| year=2014| last1=Hill| first1=Jeffrey E.| last2=Lawson| first2=Larry L.| last3=Hardin| first3=Scott| bibcode=2014TrAFS.143..817H| access-date=2014-07-04| archive-date=2019-02-03| archive-url=https://web.archive.org/web/20190203154812/https://www.tandfonline.com/eprint/nvuFmCDyamiIZp4qAMeW/full#.U7cfS_ldWQE| url-status=live| url-access=subscription}}</ref> A second study concluded that there is no difference in risk between GloFish and wild-type danios.<ref>{{cite web | title=Risk Assessment of Transgenic Fluorescent Ornamental Fishes to the United States Using FISK v2 | url=https://www.was.org/documents/MeetingPresentations/AA2014/AA2014_0314.pdf | access-date=2014-07-04 | archive-date=2014-07-14 | archive-url=https://web.archive.org/web/20140714154253/https://www.was.org/documents/MeetingPresentations/AA2014/AA2014_0314.pdf | url-status=dead }}</ref>
