That looks like the possibly GMO electric blue. The story is it's a linebred mutation (as the sale of gene spliced fish is banned in many markets), but it hit the market right around when a bunch of electric blue fish from different families mysteriously appeared. I could never prove it came from a system similar to the glo-gene story, but the timing has always made me wonder.
Circumstantial evidence...
I've never heard of anyone bragging about creating these electric and powder blue morphs, and that ain't natural for fishkeepers.
The natural colour blue acara (Andinoacara pulcher) is a nice looking fish anyway. It doesn't harm the fish. Whether you go for these fish or natural ones is just what you like.
