Cory cat tail fin regrow?

[Clentipo]

I bought an Albino cory cat from my LFS a few days ago. Only one they had and when I spotted him I could only see his head. He's fairly young only about 1 1/2 inches long. After I got him in my tank I noticed about half of his tail fin missing. Mostly the clear portion of the fin. He seems to be doing fine. He takes a breather every once in a while from swimming hard, he's pretty active. I was wondering if it will grow back completely. It seems as some has already grown back.

Tank info:

Ammonia: 0 ppm
Nitrites: 0 ppm
Nitrates: 20 ppm
PH: 6.8

20H aquarium with an Aqueon power filter. Marineland 900 powerhead. Lots of live plants and rocks to hide under. 46 watts of 65k CFL lighting.

My guess is it will grow back as long as the base of the tail isn't missing.

I have one of those who lost his dorsal fin somewhere and it never grew back. But he doesn't seem to miss it and the pair has spawned twice that I know of.
