Butterfly Goldfish?

I'm a new member here and I had a question about some of my goldfish. We've had our pond setup for about 4-5 years now, and after the first year one of them had lots of babies. Just today I noticed some of them have long, flowing fins like the butterfly koi, but they don't have the barbels. I was able to catch one to take pictures. Is this fish really one of the hybrids?
