i wouldn't i tried that before, i fed my rays more than my snakeheads, the snakeheads starting nipping at the rays, enough to make them spit it out!! why would anyone want a snakehead anyways, they need food constantly!!
Well I would say No way I have seen rays try to eat Gars big ones at that so that’s the less volatile Channas out of the equation. Then that leaves the other 80% well they will eat or just annihilate your rays for the hell of it reds kill just for the hell of it my old one would eat all it could with feeders then kill the rest so no not a good idea.
