Glofish are becoming more and more common these days in the hobby, in the last year I've seen 3 or 4 shops with a few fish for sale, they're a "Man Made" fish so are not natural in nature, but are a result of adding specific jellyfish gene's into eggs of fish.
The two species used are Zebra danio's Brachydanio rerio
and the medaka Oryzias latipes
Only some of the resulting fry take the jellyfish gene's into the genetic make up, and can then be reproduced if someone was to breed them.
They are a strange fish as they do glow in the dark.... Adding a UV lighting system they reflect UV light in a visible wavelength that we can see. With no other lighting it's a haunting sight to see these fish swimming around, glowing away.

There's 4 main colour types; Red, Green, Yellow and Purple.
But now there is what's called the Candycane coming out.

I at first did not like the idea of messing with these fish as they're great fish by nature, but Azoo has done amazing things to these fish. I have sadly grown to like them more and more as i've seen more.
As these fish are genetically altered they do breed true, and if you're lucky enough to so, do, you will have more glofish. Now the problem here is that Glofish are a patent of Azoo and breeding them is fine, but if you sell them you will then be breaking the law unless you have their authorization to sell them.
So if you was to breed them, then you're going to have some happy friends.
