Which breed of fish is this?

[Olivia286]

I have unexpectedly had some baby fish in my tank of platys, mollies and guppies and I’m trying to figure out which breed they’re from as only a few have been born & i need to isolate the pregnant so they can continue!

Any help would be appreciated thank you

I looks like a mix of a guppy and something else
