Haven't seen that for awhile
It only work if you know the background of the Bloodline(family tree) of the breeding pair
If your just basing on the information on how the fish look like
Sometime the pair will throw u an odd ball color fish that u didn't expect
Exactly. Note how it says "True black" and "True blue" in the top left corner. "True," meaning a solid line of the same genetics. I see a lot of people buying the same colored fish at the pet store expecting to get the same colored offspring, and they get surprised with a tank full of fry that are all different colors. Teehee.
