What is launching in February? GloFish LLC is welcoming a new species to its ever-expanding family of fluorescent fish with GloFish® Betta. The Electric Green® GloFish® Betta species is the first to debut within the betta category, introducing GloFish to a new audience, and will be available alongside a unique array of kits, species-specific food, water care and décor.

Where can you buy GloFish® Bettas? GloFish Bettas will be available at Petco, PetSmart, pet stores and other local independent pet retailers.

Are GloFish® Bettas different than typical bettas? GloFish Bettas offer a unique opportunity to the world of betta fish. While nearly identical in behavior to traditional domesticated bettas, GloFish Bettas produce a fluorescent protein that allows them to fluoresce under blue LED lights.

Are GloFish® Bettas injected, dyed or individually altered? No. GloFish Bettas are traditionally bred; their unique and harmless color is a hereditary trait that is passed from generation to generation.

Where are bettas found in nature? The betta is native to Southeast Asia and is one of the most popular aquarium species because of its hardiness, beautiful bold colors and long fins developed by selective breeding in captivity. The modern betta is a product of almost 100 years of selective breeding. Bettas are anabantoids, which means they can breathe atmospheric air through a unique organ called the labyrinth. This accounts for their ability to thrive in lower-oxygen water conditions, like rice paddies, slow moving streams, drainage ditches and even large puddles.

Is GloFish LLC launching anything else? In addition to the livestock offerings, GloFish LLC is also introducing an assortment of products, including a 1.5- or 3-Gallon Betta Aquarium Kit, GloFish® Betta Flake Food, GloFish® Betta Water Conditioner and GloFish® Betta Water Balance to elevate the aquatic experience, with additional launches, including plants and other tank décor, later in 2020.

Are 1.5- and 3-gallon aquariums large enough for bettas? Yes. For one betta, either the 1.5-gallon or 3-gallon aquarium is a perfect home. For a sorority of GloFish Female Bettas and/or a few community fish, a 5-gallon aquarium is recommended.  

How often should you clean your bettas’ tank? Along with proper feeding, partial water changes are the most important way to ensure that your fish are robust and healthy. For new aquariums, or for an aquarium to which you are adding a substantial number of new fish, we recommend making partial water changes after two weeks and again after four weeks, then once a month thereafter.

The Science of GloFish® Fluorescent Fish

How common are fluorescent fish in nature? Fluorescent fish are very common in nature. In fact, a recent study conducted by the American Museum of Natural History found more than 180 species of fish that are naturally fluorescent under blue light. Fluorescent fish can be observed expressing vibrant green, red and orange fluorescence patterns across a very diverse range of species, including more than 50 families.

What other types of organisms are naturally fluorescent? In addition to fish, fluorescence has been commonly observed in certain types of corals and other marine life, and fluorescence signaling has been reported in butterflies, parrots, spiders and even flowers. It has been suggested that they function to assist with things such as visual contrast, antioxidation, photo acclimation and health.

How common is the use of fluorescent fish in science? For almost two decades, fluorescent fish have been relied upon by scientists worldwide to better understand important questions in genetics, molecular biology and vertebrate development. Fluorescent fish have been particularly helpful in understanding cellular disease and development, as well as cancer and gene therapy.

Are GloFish® fluorescent fish injected, dyed or individually altered? No. GloFish are traditionally bred; their unique and harmless color is a hereditary trait that is passed from generation to generation.

Are GloFish® fluorescent fish captured in the wild? GloFish are bred by skilled breeders who have years of experience in the tropical fish industry.

How do GloFish® fluorescent fish get their fluorescent coloring? Today’s GloFish fluorescent fish are bred from the offspring of fluorescent fish that were originally developed several years ago. Each new GloFish inherits its unique color directly from its parents, maintains the color throughout its life and passes the color along to its offspring. The fluorescent protein genes are derived from naturally occurring genes found in marine organisms.

What environments can GloFish® fluorescent fish live in? GloFish are great for any home, office or classroom and perfect for hobbyists and beginners alike.

How are GloFish® fluorescent fish different than other fish, i.e. goldfish? GloFish are like other fish, except they have a much brighter nature. GloFish are available in six stunning colors: Starfire Red®, Electric Green®, Sunburst Orange®, Cosmic Blue®, Galactic Purple® and Moonrise Pink®.

Caring for GloFish® Fluorescent Fish

Are GloFish® fluorescent fish freshwater fish or saltwater fish? Like their non-fluorescent counterparts, GloFish are freshwater fish. They should not be placed in a saltwater environment.

Where can I find detailed information about GloFish® fluorescent fish? GloFish should be cared for in the same way as their non-fluorescent counterparts. In general, guidelines for maintaining a robust and healthy GloFish can be found on the GloFish Care page at www.glofish.com.

How should you care for your GloFish® fluorescent fish? GloFish are like their non-fluorescent counterparts, just with a brighter nature. They are the same in terms of care, including everything from general care and temperature preferences to water quality and nutritional needs. With a little care and attention, your fish will be a happy, healthy companion for years to come.

Who can I talk with regarding specific questions about my GloFish® fluorescent fish? If you have specific questions about your particular fish that are not answered in either of the websites noted above (including concerns about odd behavior or possible illness), contact either your local fish store or a local veterinarian who works with fish, since both are great resources for fish-specific questions. If you have additional questions, please call us at 1-800-GLOFISH (800-456-3474), 8:30 a.m. to 5:30 p.m. EST Monday through Friday.

Is there a recommended tank size and/or stocking density for GloFish? Other than the GloFish Sharks and Bettas, GloFish® fluorescent fish are schooling fish. Because of this, they can thrive in relatively high densities compared to many other fish. Recommended stocking densities vary depending upon the literature source, tank configuration, filtration system and other factors, so making a specific recommendation is difficult. Consulting with the experts at your local fish store can be helpful before starting a new aquarium or adding to an existing community.

What types of fish are GloFish compatible with? Like their non-fluorescent counterparts, GloFish fluorescent fish, except for bettas, are community fish and will “play well” with other fish. However, not all fish are this way, so it is generally advised that people check with their local retailer for specific information on whether their existing fish can peacefully co-exist with GloFish. A couple of species-specific notes: GloFish Sharks can be semi-aggressive, so we advise keeping only one shark per aquarium. They can, however, be housed along with other GloFish Tetras, Danios and Barbs. It should also be noted that GloFish Barbs can potentially become aggressive if they are not kept in groups of five or more. This is not necessary with GloFish Danios or GloFish Tetras; while they prefer to be in groups of five or more, they will not become aggressive in smaller numbers.

What should I do if my fish is behaving in an unusual or aggressive manner? There is a relatively wide variety of behaviors that fish can normally display. However, if you have any doubts as to whether your fish’s behavior is normal, it is recommended to contact your local fish store or a local veterinarian who works with fish. Both are fantastic resources for fish-specific questions or concerns. Having adequate décor can help distract fish and break up territories.

What should I do if I have a question regarding my GloFish aquarium kit? Please call GloFish at 1-800-GLOFISH (800-456-3474), 8:30 a.m. to 5:30 p.m. EST Monday through Friday or email GF-Support@glofish.com

Displaying GloFish® Fluorescent Fish

What is the best lighting for GloFish? The GloFish Blue LED Light is the ideal aquarium light for GloFish, which makes GloFish décor and fish fluoresce even more brilliantly. However, GloFish will thrive under a typical white light.
