It was bought as a spotted gar the store couldnt tell me anything else, but what confuses me is the dark stripe on its dorsal surface from nose to tail. As you can see it has hardly any spotting besides on the tail
the trident mark isn't something that *defines* a tropical gar. based on the pics, its definitely one of these: spotted/florida/shortnose. i'll let the experts tell you more. how big is it? that info may also help.
