Thanks for sharing.  Truly a breathtaking species to see in the wild.  Would be a shame to lose them.

Is interbreeding occurring everywhere that variegate darters have been introduced?  In some cases (I don't know about darters) hybridization is a problem where habitat alteration interferes with the natural behaviors and that normally serve as species isolating mechanisms.  I recall reading something about this with introduced populations of red shiners, where hybridization was less common or less successful in less altered habitats than in more altered ones.  The hybrids had competitive advantage in the more disturbed streams.   If so, then habitat improvement needs to be part of the long-term strategy.  But if the hybrids have competitive advantage even in high quality habitats, then there may not be any feasible way to reverse the ongoing hybrid introgression.  Nature may consider the hybrids as an "improvement" even if we don't.
