French hobbysists have been there, but I do not think any Americans have made it that way yet. Joe Rusty Bill and I brought back nanos from Rio Robalo a few years ago. Other nanos in the hobby may have come from Europe, meaning they may be altos. The river drainage that they came from may be the only difference.
This is one of those pet peeves for me. The altoflavus description was published in a non-peer reviewed journal. Informal American rules do not allow or recognize such descriptions (such as could be potentially published in B
. Yet these same scientists will recognize such clap-trap from across the pond, and Kullander loves the non-peer reviewed French hobby stuff.
As such I don't recognize it as a valid description or species. If no one else did either, it would go away. However, it seems to have slid its way into common usage.
Don Quixote anyone?
Its the mysteries of life that keep me going.
