Hey,
I was at my local pet store, Petco. I saw some orange tetras. They had the neon stripe but it was a bright neon orange. I read somewhere about injecting fake color into these kind of fish. Is this a real color for tetras or do you think this is what was done to these fish?

Next...if they are really that color (and not injected) would they be ok w/ my 3 neon tetras in my 2 gal. tank. I heard tetras should be in a bigger group so I thought about buying more, could I mix them?
