An alligator would never come into contact with a dolphin given habitat differences. Crocodiles (particularly the American crocodile of the New World and the saltwater crocodile of the Old World) may occasionally be found in dolphin habitat. Interestingly enough (and tragically) a dolphin was killed by an American crocodile along the Caribbean coast of Costa Rica in 2011, although this must be a very rare occurrence.

No you can not turn to an alligator if you eat green french fries.
An Orca (killer whale) will hunt and eat Dolphin.

Dolphin doesn't eat tuna. Tuna are to big.
A large shark would be a great predator of the alligator gar. Bull sharks can take down a giant alligator gar easily. Alligators and crocodiles can eat alligator gars if they catch them. Alligator snapping turtles can catch small alligator gars, and will only eat dead giant alligator gars.
no, you should keep your alligator gar with your fishes or else your alligator gar will eat them.
