Would it be possible to have a warmouth only pond? Stock FHM, Gambusia, Northern Redbelly Dace, Sailfin Mollies, and crawfish. Then have Warmouth as the prime predator. This would be an ideal small pond setup. About 1/4 an acre. Warmouth are predators that reach 12" and have a larger mouth than most sunnies. They also reproduce very little. So would this be a feasable deal? Getting the fish would be the hardest thing.
