A red rainbow is a red rainbow is a red rainbow....or is it?

I am so confused! Years ago I had a New Guinea Red, which later was identified as Glossolepis incisus. I have looked for one for a long time. Several fish stores sell Millennium Red which I learned are Glossolepis pseudoincisus. One fish store owner claimed the Millenniums were often just Irian but that most fish stores don't know the difference and pay more, ditto to the consumer. Some stores are selling "red rainbows" and others are selling "Red Irian", or have tanks with tags that say Red Irian at a higher price that the ones labeled "Red Rainbow". Good grief.
  Then there are tanks labeled Glossolepis Irian, and when I challenged the store owner on the name, he got really irate and said "if you want a red rainbow, buy one of these...regardless of what you call it, a red rainbow is a red rainbow, is a red rainbow".  No, I didn't buy one.


Another fish store owner shook his head and told me, "no wonder you are confused....they are all names for the same fish". I don't think so....the Millennium nor the Irian are as big, as humped, or long snouted as that beauty I had so long ago.



Can a rainbow enthusiast clear this up for me....and where can I find them? Our local stores seem to only carry irian or millennium, or "Red Rainbow" and who would ever know what species that actually is (the fish store won't!!).


Not sure where this forum is hosted; I'm in the U.S.A.

Anyone here able to ID/differentiate these reds?
