not idea but my friend's ...
and i thought the same, the biggest population spreads is green so the most logical n possible was green aro.
but my friend got some funny n interesting views abt that.
he said super red got the most complete features that no other aros have.
- horse shoe marking even indistinct compare to green or banjar
- most varied color base, others may only have silver, blue, purple, green. (its a weak reason i think)
- it always gets cross back
- the hardest to bred n longest period to mature sexually
- it can show snake pattern/batik marking also (most of colored aros could show snake pattern i think)
