My new swordtail is acting alarmingly. I was in bed, about to fall asleep, and I looked in my tank, and saw something orange swimming back and forth very rapidly and recklessly. I got up and sure enough my swordtail was laying bottom up at the bottom of the tank, not dead, but not moving other than to breathe. I netted her, and attatched the net to the side of the tank with a clothespin, just so they other fish can't get at her. She's not swimming, just laying upside down, occasionally breathing. I don't know what to do

Will she be ok? can fish have seizures? it sure looked like one. She might be stunned, I'm pretty sure she hit the side of the tank. If she dies, since she was recently having babies (just released another one this morning) is there a way to save any live fry she might have? Should I squeeze her? Please respond ASAP!
