So I was missing one of my guppies. I finally found him in the filter but when I tried to get him he jumped and fell behind the entertainment center, about a 3 foot fall. I quickly got him though. He was out of the water for probably about 60 seconds at max. I put him back into the tank and he is kind of doing ok. He is breathing quickly and his tail is "shivering". Is he going to be ok?

I just added aquarium salt earlier this evening, about 6 hours ago so I can't add any more to help him with the stress. Poor guy. :(
