Molly playing dead?!?

Your fish likely has a damaged swim bladder. It is a sac inside the stomach area that helps maintain balance and proper bouyancy. These fish don't play dead. The swim bladder could be damaged due to exposure to too much ammonia and/or other toxins in the tank or possibly due to parasite. I don't think there is anything you can do --- if she can eat and survive, then she may be OK, but my guess is that she'll eventually die.
 
My betta has had this infection, I did a water changed and fasted him two days and it did the trick. But I don't know if that'll work for your fish.
 
Fish isnt full of food. It pooed out some greens, nothing else, haven't fed her.
Still don't know what causes the seizures/tremors/head shaking.
 
So since I can't fix her, how do I do away with her quickly and painlessly? I don't have oil, do not want to knock it out or cut her head off and I rather not put it in my freezer, so those wont work. Anything else I can do?
