Adding color to guppy lines
I inherited a family (two generations, it looks like) of orange guppies from a friend. It appears to be a good mix of male/female (roughly 1:3, though I haven't officially counted).
If I want to add some color variety to future fry, is it more likely to succeed by adding males of the new strain, or females? Assume that I plan to keep the ratio the same.
I'm not trying to be too scientific about this, but if I'm going to tinker with the fry outcome, I'd like to get the most bang for my buck.
