I wish that I had all the answers, but I don't. Plenty of info has been posted in this discussion, more then enough to get someone started down the right path.
FYI - 8-12 metres of rain doesn't happen overnight. Dominant loaches seldom if ever grey out, unless under stress. Greying out is typically seen in stressed out fish, or when sub dom fish are establishing or fighting over their pecking order in the group.
The local Petland here had some F1's a couple of years ago, very small (3/4" TL) and cost the same as 3-4" loaches anywhere else. Most stores won't bring them in due to their ultra small size, and the price tag attached to such a small loach. You would probably have to find a farm in Florida & import directly in bulk.
