are glofish eletric green tetras dyed?

  • We are currently upgrading MFK. thanks! -neo
No. DNA modification using DNA from bioluminescent bacteria.
 
Nope, none of the GloFish brand fish are dyed. They are genetically modified with a fluorescent protein which cause them to have the color they have.

I didn't know they added Tetras to Glofish until a few weeks ago when I saw them at Petco.
