Take the feeder out of its mouth. I had to do this the other night with my fish, it got exhausted for trying to swallow it for hours and was having trouble breathing etc. Get the fish in a net and carefully grab the feeders tail firmly. And very gently pull back, your fish make rock around for a little bit and this helps a little. Dont try to force it out fast, but do it slowly Also, when you net the fish bring it up to the surface and have it still in the tank so that if the fish wiggles he falls back in the water. It mgiht take a few trys easing the fish out but it sounds like thats what you gotta do, because the Bass will die if it cant swallow it.
