I have 5 healthy 2+inch babies in my pond! I think the mom is a long finned Shub- blueish white scales with lots of small black and red dots. Dad could be one of many goldfish(all shapes and sizes).
3 of them have the same markings as mom, but regular tails.
1 is mostly orange with one big black dot on the side, with a long tail.
1 is blackish orange with the longer tail.
