They're on par with what I was expecting. They're fast growing as far as geophagus go.Are you finding their growth rate to be slow and do you expect that the adults will look much different than the Rio atratos do?
I've attached the photos Jeff sent me of the two collection points. As you'll see the Atrato maintain more of the black coloration and have less blue in their fins. Also, my female has zero coloration. I'm expecting the Upper Rio San Juans to maintain the red lining in their fins for both sexes.
