The exact species of the common aquarium Tiger Barb is something we still are not sure about, as there are five wild species sharing very similar markings. But the aquarium fish has been commercially bred for decades, and actually been weakened through the process. Along the way, colour variants have been selectively bred, including the albino, golden and green forms. I have not heard of an "electric" green, but would caution you just in case.
Sadly, the TB has also been subjected to the use of injected dyes. The above mentioned variants were not obtained this way, they were selectively bred. But this "electric" form may well be injected. All such fish should never be purchased by any serious aquarist. There is only one way to stop this cruelty, and that is by not supporting it financially. Also, any store that carries such fish should be told that you object. Nothing will change otherwise.
I am not saying the fish you saw are such; just a caution they might be. You mentioned a similarity to the Glofish. This is another fish that should not be purchased for similar reasons; it is banned in Europe and the UK.
