I just bought a juvenile "exasperatus" from my LFS for $5.99 (I thought the price could possibly help in identification 
).
I looked up exasperatus and there appear to be two or three different genuses with exasperatus species, but none resembles my fish at all.
Here's a rainbow with a horizontal, blotchy black bar like the new fish has, and somewhat similar overall coloring:
And here's my fish (looking pretty washed out - the horizontal bar is completely invisible - but not to worry, he seems to be doing fine otherwise):
There's also a prominent black blotch on the dorsal fin, which is red across the top. The coloring sort of reminds me of a Ram with the yellow, turquoise and black this fish has when he's more saturated.
