I have my G. multisquamata breeding now as well as Betotia sp. "Ankavia River" and M. duboulayi.... just not enough yet to sell mops. Still young adults being that I bought them last summer at 1". Not a bad start though.
I agree, there are very few rainbow breeders out there. All r'bow forums are non-US based. Very annoying.
What species are you looking for, out of curiousity?
