if you have pics we can ID the fish right away. if it was purchased as a young of the year fish in the past 6 years, then it is very unlikely a croc I as they were only produced for 1-2 years in appreciable numbers.
BONUS - answer is....ANOTHER croc I...wish I would have hung on to both of these guys (and an eventual 3rd that I got from Richard, that eventually went to Chad on AP - was unfortunately lost in a big die-off).
the fish in all the quiz pics actually broke its back so i had to euthanize it...guess that was the shortnose attitude coming out. either way, we're still using it for some other work--
