Shortnose are Lepisosteus platostomus, and crocodile gars are hybrids of Atractosteus spatula (alligator gar) and assorted Lepisosteus species. Croc gars will get too large for your tank, as will alligator gars (see the pic below). If you want to be sure that you can keep the gar that you get for life, then shortnose is the only way to go.Dino88 said:the width of my tank is 3 feet and the lenth 2meters and 1meter high.how bout the crocadile gar?is he the short nose?
