If by gator trout you mean speckled, I don't think it would work. They are saltwater fish. They can tolerate very low salt but they do need salinity to some degree. I also think you mean bowfin, not bow fish.Gator trout if you get a baby till it out grows your tank florida gar small snake head ( pending legality ie where you live ) bow fish and a few war mouths are fun
