Can a Milk Snake Eat Fish?

[Cricket1234]

So I have been inactive on the forum lately, and I have been trying to kind of catch up on everything. Before I post this, please remember I am not doing this out of cruelty but more for the health of my animals and for a view into the predatory behavior of snakes, as well as an interesting scientific experiment. Here it goes.....
So I have a ten gallon community tank in which I have been very proud of. But I have always had this one yellow GlowFish neon tetra that has been starving my other animals, especially my African Dwarf frog. Whenever I feed all my animals, this one fat little fish bullies all of the other fish away, even his own school. He then tries to eat almost all of the food. I try to feed him separate, but the only tank I have is strictly quarantine and I can't use it for feeding. The fish is literally (No exageration) So obese that he is the equivalent to a 700 pound person. I want to get rid of him, and nobody will take him due to his tendencies. So the idea came to me to feed my snake the fish, as I want to see a.) If the snake will constrict on live prey, and b.) how a snake would hunt in its natural environment. I would like to use a mouse I just can't deal with feeding such an intelligent mammal to a snake alive (but I envy those who are brave enough to do it) Will this make my snake sick or die? Just checking ahead of time. Thanks guys, for answering and reading my long post!
