My cousin got his spotted gar around the same time that I bought my red swamp crayfish. Five months have passed since then and his gar has attained a considerable length of a foot long. Unfortunately, his parents aren't comfortable with him keeping a fish that only eats live prey and want him to get rid of it. That's why he asked me whether I could take care of it instead. However, my tank is already inhabited by my crayfish. He's extremely agressive as demonstrated by the fact that he literally shreds the feeder shrimp and mealworms that I give him. Is there any possibility that he would leave the gar alone? Or would he attack the gar with his pincers? They can inflict a very painful injury as I know from personal experience(He pinched me once when I was feeding him a live worm and it hurt like hell). After all, although it's twice his size, it's still a fairly delicately built fish and I can imagine those awful pincers doing some terrible harm. Any feedback would be greatly appreciated. Thanks.
