Red Belly On Rainbowfish

My rainbowfish, Dash, has a red belly. I have looked up his kind of fish and they have orange fins without red bellies. I don't know what it is. Is it normal and if it's not is it curable what ever it is.
He is a parkinsons rainbowfish.
Info:
He is in a 60 gallon with 5 others.
The tank is cycled. Parameters normal.

Please help

Anyone?

 

Is it an illness?

 

Pictures?

 

Agree. Need pics.

 

He's too fast. I can't get decent ones. Can you wait a minute?

 

 

Sorry he's a bit fast. Can you see it. It's gone down a bit since earlier, but it has been on and off for a few days now

 

I can't really see it at all. This appears to be a young BoesmainI rainbow. Is that correct?

 

No he is a parkinson one. Unless he was sold wrong. He does look different to Braveheart and Crossarrow though and they are the Boesmanis. Dash is with 3 others who all look like him.

 

That would explain the red. This is a young fish just starting to color up. Parkinson's have bright orange color as adults some are even red. I don't think you have anything to worry about, but keep us informed if you notice any other symptoms.

 

Oh ok. I looked it up on the internet and I could only find orange that's why I got worried. I'll keep you updated and thanks for the heads up.
One last question: How do you tell males from females? I heard it's something to do with the fin but I'm kinda confised by it

Honestly I'm not sure how to tell, but I think the males are more colorful. Also there color may look different depending on the lighting you have.
