I recently came across a 2-3" alligator snapper. I have him in a 75 right now. I really want to put him in with some of my larger fish. I have a 150 that I am using to grow out some p bass, gars and a tsn. Would he be compatible if the smallest fish is around 6". I would hate to introduce him only to have him eat my fish. I have a 5000 gallon pond in the basement but I'm afraid he would be a snack for my big rtc and or my larger p bass. Any suggestions would help. I had turtles when I was younger but never really got into them. Thanks
