Are these shrimp a dye job or for real?

Blue is quite a common color for most decapod crustaceans raised in aquariums. I would not doubt it is natural, if not a photo of a very freshly moulted shrimp.

Probably not dyed, the pigmentation of the dots seems real enough for me, though they remind me of a blue version of RCS (though RCS are actually a color morph themselves).

They're real. There's also blue tiger shrimp, with lines down their backs.

I have heard that people dye shrimp. Is this true. How do you tell the difference? Are there real cobalt blue shrimp. Here is the add this shrimp came from. Do you think it is legitimate. http://www.aquabid.com/cgi-bin/auction/auction.cgi?fwinverts&1195339357


I successfully breed blueberry shrimp - see http://shrimp4pets.com/BlueberryShrimp.htm

I don't think any small aquarium shrimp can be "dyed" - think about it, they are sensitive to water changes, temps, foods... I don't think such a delicate animal could survive a dye process. Plus, these animals molt. Any dye would "shed".

As for diet being responsible, every aquarium shrimp benefits from a good diet...in color, health, having babies etc...

I've noticed that dyed fish and invertabrates tend to have a uniform color, whearas naturally color fish have stuff like spots of color (like this shrimp) and generally un-uniform color.
