crashsmAshley, tattooed fish.... not much different than the glofish you used to own for a short while..... well once upon a time anyway... now there just born with that tattooed gene.
Ehhh... tattooed fish like the parrots there are done on a full grown fish (somtimes juvies too) using dyes and paints... sometimes it's tattooing with a needle like those, or in the case of "jellybean parrots" it's generally dye dips.
They don't last long, usually over 50% of a batch of tattooed fish die before they make it to the stores and any that do survive have a shortened life span... the color also fades given time. The color doesn't breed true.
Glofish on the other hand are genetically modified zebra danios, the original generation or two had their genes spliced with a flourescent protein gene (derived most likely from corals or jellyfish)... their color is permanent and it breeds true, though if you do breed them you can't call them Glofish, unfortunately they're trademarked

and so far as I've seen it hasn't caused any detrimental side effects to the original species, there are fakes on the market that are dyed zebra danios but those are generally sold under GlowFish or some other name to avoid copyright infringement lawsuits
sorry for the length lol
