I had a male swordtail jump out of a bucket while i was upgrading tanks, must have been out of the water for at least half an hour probably more. I was really surprised at how he recovered, I just put him in the tank as soon as possible and kept the water really clean, I also used melafix to help speed recovery and help prevent infection. His fins were all dried up and he lost most of his sword, now he's perfectly fine and his tail is grown back really fast. I don't suggest the breeder net unless you have other fish that would harass the injured fish, just let him find his own safe place and keep an eye on him. The net may cause more stress to an already stressed out fish
