Hello, I have a 25" alligator gar, he's been with me for a whole year now, I raised him since he was 3-4 inches. He bit my mom's finger once when he was around 12". So my question, if I want to get another fish to be with my 25" alligator gar. What size should that fish be that it wouldn't be eaten by a 25" alligator gar?
