ok i have been out of town and all over the place for the past couple weeks, but time to get back on track!
ANSWER:
Tropical Gar, Atractosteus tropicus
Thanks to all who guessed! I'm recording this one as no correct answers given as Madding was lucky enough to wait until there was confirmation that others Atracts could be eliminated
This particular specimen photo was taken BEFORE tropicals were brought in for the hobby...I borrowed it from the University museum, which has one of the largest fish collections in the world...so keep in mind all those are fair game
