I don't know what breed my fish is!?

My Axolotl loves feeder fish and so we bought some for it. Just lately my Axolotl died and I am left with the left over feeder fish. I looked up on the internet and they look like rosy red minnows but they have red fins and a neon black/blue stripe down their sides, they also have a spot on the tail fin. The tips of their fins are neon green. They are the size of rosy red minnows and they are see through like them too. Please help me!
