Most generic pet stores call them painted, so you can understand the mistake.chromedome52 said:Well, we're getting closer. The top one is a Blue (more specifically, non-yellow), not a great one, but definitely genetically blue. The lower one is not a Painted, it is a Tuxedo. The black Tux marking can vary from heavy to light, but it is still a distinct band down the flanks. Painted is a bunch of random black blotches.
I don't know for certain the genetics of the blues. However, I believe it is a pure recessive, which means breeding it to the Red Tux will result in either Red or normal Green Swords, but they would be carrying the blue gene. It gets more complicated from there.
The Red Tux is a strain that I know very well. The Tuxedo marking is a dominant gene, but is only expressed when heterozygous. A homozygous tux will usually die in the womb, or shortly after birth. So a Red tux is likely to produce some Reds without markings. Red is also a dominant gene, but it is seen the same whether heterozygous or homozygous. Only way to find out what the genetics are is to breed it with a non-red strain and see if any fry are non-red.
So, likely you will get Red and Red Tux fry, with a possibility of Green and Green Tux fry. Or maybe not. Considering that store bought fish aren't likely to be proper lines, I would just let them breed and see what happens. Only thing I can say for sure is that some of them will have the Tuxedo markings.
