Actually, you CAN get a crocodile gar...you just have to catch it yourself! I have a croc III mounted on my wall, 6' 3", was too big for my tank. But, I've seen several that were smaller, in the 3-4 foot range. Never seen small ones, although I suspect you could breed your own pretty easily. The male alligator gar often spawn with the large female longnose in east Texas.
