Scientific name: Danio rerio
GloFish are a patented brand of genetically modified (GM) fluorescent Zebra Danio Danio rerio. GloFish were created in 1999, when scientists in Singapore inserted a gene from jellyfish, which produces a green fluorescence, into a Danio rerio embryo. According to the patent holder, Yorktown Technologies, "GloFish® fluorescent fish were originally bred to help detect environmental pollutants. By adding a natural fluorescence gene to the fish, scientists hope to one day quickly and easily determine when a waterway is contaminated. The first step in developing a pollution-detecting fish was to create fish that would be fluorescent all the time. Scientists soon realized the public's interest in sharing the benefits of this research, a process which lead to GloFish® fluorescent fish." GloFish were first made available in 2003, and are the first genetically modified animals to become publicly available as a pet. GloFish are generally hardy but some varieties are prone to infections at temperatures higher than 77 deg F.
GloFish are currently available in five patented colors: Starfire Red, Electric Green, Sunburst Orange, Cosmic Blue and Galactic Purple.
They are a favorite schooling fish (preferably six or more) for community aquariums because of their relatively peaceful nature (they will nip fancy-finned tankmates).
GloFish, like Zebra Danios, can adapt to different tank situations. They enjoy swimming around well-planted and decorated tanks, but do well even in newly established aquariums. Because they are hyperactive and tend to escape by jumping, aquariums must have a good-fitting cover.

Great for kids
My parents inherited some Glofish from an uncle who moved and they were so fun to watch and have around. They gave us 6 of them, along with their tank. They each were named by their young daughter (although I can't remember all of their names). When we got them we had an almost 1 year old in the house, and he loved them. He would walk to the tank and loved to watch the fish, so that was a lot of fun! The fish were easy to feed, just a pinch of food every few days. When I moved out, my parents also moved from their house around a year later and took the fish with them. They all survived the move and are actually still alive today. I'm not sure of their life span, but 3 years and counting seems long for such little fish. .

Copper works when dosed correctly
Copper sulfate is a heavy metal that when dosed correctly, kills Chilodonella. The idea is to kill the parasite and not harm the fish. Dosing is based on the alkalinity (carbonate hardness) of the water. Copper toxicity increases as carbonates decrease, so a lower dose is required in low-alkalinity water. Charts can be found online. You'll need a copper test kit and alkalinity test kit to dose in the best manner. Otherwise, follow the directions on the treatment label.Avoid chelated or complexed copper medications. They are not effective..
