The term GloFish is actually a trademarked brand for genetically modified zebrafish. Zebrafish are found in the rivers of India and Bangladesh and are primarily tropical fish. They have long been sold in the U.S. ornamental fish market.
Dr. Zhiyuan Gong and colleagues at the National University of Singapore (NUS) first developed a glowing fish by extracting green fluorescent protein (GFP) from a jellyfish and inserting it into the zebrafish embryo. Their goal was to produce a fish that would be able to detect pollutants in the water by fluorescing in response to various environmental toxins. The NUS team developed a red fluorescent fish by adding a gene from sea coral, then a yellow-orange fluorescent fish by adding a variant of the original jellyfish gene. A later team from the National University of Taiwan developed a fluorescent green rice fish, known as the medaka.
Later, the scientists from NUS met with Yorktown Technologies giving the company the world-wide rights to market the the GloFish. The company introduce the GloFish to the U.S. market in 2003 after two years of extensive environmental research and consultation.
Glow fish are only Zebra Danios that have had a jellyfish gene added biologically. They will usually go down to the substrate to rest but sometimes they will rest amongst the surface plants.
The really hard question is: "How do you know when they are sleep-swimming?"
Siamese fighting fish do sleep. They are the same as all fish. When fish sleep they don't close their eyes because they don't need eye lids to protect their eyes, instead they just rest on the bottom of the aquarium with their eyes open.
Get a small Aquarium Fish Net, get the body of the Fish, put it in the toilet.
no, you cant steal fish in happy aquarium
It depends on what kind of fish, and the size of the aquarium.
Fish food
Fishing in an aquarium; aquarium fishing is when you scoop fish out of your tank with a net.
yes you can
No, it is a "terrarium." An "aquarium" is for fish.
an aquarium or habitat
They are "Brachydanio rerio" aka Zebra Danios that have had a jellyfish gene added scientifically to make them glow.
It is not possible for the fish on "My Sim Aquarium" to have eggs. All fish must be purchased from the pet store.
