At one stage, good quality Moscow Blacks are readily available in our LFS. They have very black body and very little iridescent. Picture shows my earlier Moscow strains where I selective breed to make the dorsal of the female longer, bigger and broader. I don't keep the Moscow Blacks anymore, but their genes are very much incorporated into my new Moscow Chocolates.
The signatory traits of Moscow strains is big dorsal, big body and tails. The caudal span is also generally broader and extend more than do other strains. However the tradeoff I found in Moscow strains is it is difficult to stabilise the caudal to a good degree of delta (triangular).
