Freakishly elongated fins on cory catfish?

ILOVEBETTAS

It's Cory Lover's cat!
My palateus cory cat has freakishly elongated swimming fins (sorry, I forgot what they were called) and a freakishly elongated dorsal fin. I wish I could get pictures, but...

The fish's fins are about 2x the length that i would call normal. He is about 2 in. long himself and his fins are 1-1 1/2 in. long. His dorsal fin is always drooping. Is this normal? What's wrong? I've never seen this...
 
You probably have a longfinned variety. Nothing unusual about it, it's just the way they have been selective breed.
