>>> Hmm, the green tiger barbs i have seen look like botched up Tigers, not very attractive IMO.
In actual fact sanj, that is exactly what they are. A good Barbus tetrazona should not have any dark scales between the vertical stripes. Such scales would be classed as a fault on the show bench. Intense breeding for the trade throws up many substandard fish with these dark scales. People then start selectively breeding them, and then breeding those with the most dark scales together until darker and darker fish are produced.
I don't like them either, but whatever rocks your boat as they say. At least they are not hybrids, genetically modified or dyed/painted. Due to the small gene pool, they tend to be weaker then the wild types.
