Rainbowfish Identification

[Finntastic]

Hello, I just bought what was labeled as a Australian Rainbowfish but when I put it in the tank I noticed that it has lighter coloration and has different fin colors. All I know is that one of my rainbows is trying to mate with it and my other rainbow is attacking it. (Lovely welcoming committee) Will post pictures later.

It's pretty young from what I can see. They usually color up more as they age. Possibly a banded rainbow?

Maybe a deepwater slendida rainbow, but it's a little hard to see exactly. It may just be very young.

It looks a lot more like a juvenile banded rainbow than a deepwater slendida rainbow.
