Thanks for this great info. Where do I send my fish for DNA testing? Seriously, I wonder if that's what it's going to take to sort all of this out. I was also hoping to hear more about differences in the lateral band, which I guess I thought was an important difference in the variations. My male has a very straight but slightly broken lateral band (which he can make almost completely disappear), while others have more of a zig zag lateral band. Maybe it's not important though. I also found it easy to sex these at these store just from the very extended ventral fins of the males. - -Doug Brown debrown@kodak.com
