Identifing this fish

Hello

I know its a guppy but I have a fish that has a guppys body but has a short tail.
I have tryed to edit the guppy so it looks like the fish im on about.
Mine is goldish and on its spine it has colours which change from pink to blue to purple when he changes direction in the water.
I dont know what it is if you can get a picture from google that will help and I can say yes or no, I cant get a picture because he/she is to fast to take a photo of.
If you think you can help me please leave a reply.

Thanks for your help and time Grayshark
