Overview

What do you get when you cross one of the easiest-to-care-for freshwater fish with the brightest new breakthroughs in the aquarium hobby? The perfect starter fish for your desktop, kid's room, or specialty setup!

Fluorescent GloFish® are the first designer-bred Danios (Zebra Fish) to come in five neon colors: Starfire Red®, Electric Green®, Sunburst Orange®, Cosmic Blue®, and Galactic Purple®. GloFish® are not dyed and their color, which is inherited from their parents, does not fade!

Original generations of GloFish® were genetically enhanced as embryos to help detect environmental pollutants and advance scientific research. Now every generation of GloFish® is born with its amazing color! The brilliant hues are produced by a fluorescent protein gene which occurs naturally in some marine organisms.

Keeping GloFish® is as easy as keeping Danios. For best care, keep this peaceful fish by themselves in small aquariums or in small schools with equally non-aggressive fish. Since they are omnivores, feed GloFish® a varied diet of flake and frozen foods.

Approximate Purchase Size: 1" to 1 - 1/4"

Customer Testimonials

Tabby S Bloomington , IL
I have a children's tank for my 3 & 5 year olds. The glow danios are perfect for their playroom. Dark rocks and a black light bring out the bright colors the best. The only thing I have noticed is that the largest seems to be very aggressive with the 2 smaller fish. They are very easy to maintain and I enjoy sitting in the playroom at night and watching them myself.

I have all of the glow fish and love them! I keep them in my fluvial chi. They are a great pet and shine whenever I turn off the lights. This is a great fish for kids and adults!
