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.
I forgot to mention; even "rainbow" articles/descriptions online have conflicting information on the names and or the regions they are from, or differences in the species. So I am hoping for a science based reply/source from people who know what they are talking about...not just 'posting' information from other resources.
Hi there!! lol. It is confusing! The admins/mods of this forum are based mostly in North America(US and Canada), but we have participants from all over. For faster responses, you can try our fb group Rainbowfish Live where there are daily discussions about bows.
Here is the best website for Rainbowfish information....
The two "red rainbows" are g.incisus and g.pseudoincisus. There is some difference in their scale patterns, undertone colors(silver vs gold) and size. It is all pretty well listed out in the species descriptions(links below). G.pseudoincisus are smaller, more silver undertones, have fairly straight scale rows, and are known under the common name "Millenium" where the g.incisus are more likely to be called something along the lines of "Irian Red", get bigger, are more bossy with other fish, and have odd scale patterns. The fun part, is that a lot of the "red rainbows" available from petshops are probably a mix of the two species. But, there are some hobbyists and at least one Florida fish farm working with pure strain g.pseudoincisus. There is also an albino version of g.pseudoincisus.
