Joe, please forgive me if you think I am rude. I am really not rude. But boy, did this post make me laugh!
And seriously now, if they look fine I don't think you should be worried. But observe them closely for a couple of days. Did you notice any marks on their bodies (ex. something wrong with scales or fins) that you think could be the result of the fall?
If they look fine, the most that could be wrong with them is probably a shock from the fall. But they should be OK after a short while
