In my colony of snow white guppies (short tailed and blonde bodied), there's one female that has got a red tail instead of a white one. Not really weird for they do carry the magenta gene. And even with magenta on blonde, red coloration can be developed. The question remaining is: Will she produce the snow white trait in her offspring within this colony? Well, she's pregnant, so, I have to wait and see. I'll leave her in there for now.
