Which Gar Species Do I Have Exactly?

Hello there, the day before yesterday I was at the nearest LFS standing between three Gar species. One was what I believe a Shortnose Gar swimming with a two short and broad snouted Gars. They were all juveniles.

On the other side of the aquarium was a nice patterned Gar which I assumed was either a Florida Gar or a Spotted Gar. It was a juvenile as well, about 5 to 6 inches long. I wanted to choose between the broad and short snouted and the spotted type Gar although I had no idea which one was exactly the Spotted Gar as the broad and short snouted had spots all over its body and fins as well except on top of its body which was just dark.

Well so it's clear I am new to Gar, due to the attraction I had to that broad and short snouted Gar I baught it! such an awesome snout like the Saltwater Crocodile. The fish is a beauty, about 5 inches long and it was great to see it cruising near the surface like a Crocodile and BAMM!! lightning fast striking at feeders, and those teeth..impressive. Still unsure what species it was exactly that I asked a fish forum and was told that it's the Alligator Gar! was I not shocked ( Pictures below, or is it the hybrid Crocodile Gar? ). All the ones responded said it was the Alligator Gar.

Although I was very attracted, I had to rush to the LFS and tell the shopkeeper about my situation ( I can't handle it as I live in an apartment ), he agreed to trade with what I believe is a Florida or Spotted Gar ( pictures below ). I think it's a Florida Gar, isn't it?

Cool, so that is the Alligator Gar that grows to 10 feet in the wild? Why the pictures of them that I see are almost or often without any spots? Check out these pictures below I found online, an Alligator Gar right? Unbelievable to see how from this lean and nicely patterned appearance they literally become a monstrous fish that we can see in the following picture looking like a different species.

So the other is a Spotted Gar huh? How do you tell that? Because one had said it's the Florida Gar. So it's confusing, I know both Florida and Spotted Gars have spots, Florida Gar's throat has no scales unlike the Spotted Gar's. This one's throat is plain black and looking like a soft skin. Last night when he caught a big feeder the skin stretched that it became transparent showing the feeder inside.

Man, a Tropical Gar? Here are pictures of the Tropical Gar from Primitivefish.com, wow they do look similar to mine!

Ok here are more pictures of the one I have, not perfectly clear but it does give you an idea.
