I bought 3 glofish last night, and I may just have to get a whole new tank just for myself and these beautiful fish!!
They're a specially bred thype of Danio.. and essentially are just danios... BUT...
They've been genetically altered to have DNA from jellyfish that make them flourescent! the first fish in the breed is altered, and then just bred... the color is just passed on. :)
This is a picture of a regular zebra danio... We have 3 of them in our tank already. I wonder if they'll all learn to get along and school for us. :)
