These are F1 umbies from TNT aquatic's $500 wild male from back in august 07. Each fish is around 5". the first two pics are Fish 1, the 2nd and 3rd are Fish 2, and the rest after are all Fish 3 (I think Fish 3 is a male). I know this is a difficult fish to sex, but many of you out there are better than me at this. Let me know what you guys think!
Thanks
