Ironically, I had a drop that was full of babies colored like the "colorless with the stripe", except my fry had multiple stripes. Any where from two stripes, all the way up to five stripes per side! In the same drop, out of about 25 fry, I had three that were pale yellow with black fins and lips. The yellow are actually my favorite platy fry! They are a couple months old now and sexing out. Sadly the stripes do go away, at least mine did. The will start to get a blue to green tint masking over the stripes.
I thought it was ironic that our drops held the same color genetics but with a different ratio. I'm currently at work, but I will for sure post pics of my fry in the morning! And there was a fourth yellow fry that came in the next drop who has a black tail, black lips but "it's" top fun is red.
they came out of a blue female platy crossed with my red wag male. There were also some light orange fry with a green shimmer masking the orange.
