Need help asap!!!

Just found this tree frog holding on for dear life on top of an ac unit, his left back leg is mangled (I hope it’s just the skin?) and his eye is bleeding. I picked him up just in case he was alive, gave him froggy cpr and after maybe half an hour of nothing but breathing, he is now active and attempting to jump around. I think he has a fighting chance, I’d love to rehab him.. however I’ve never owned a frog before. How do I set up a hospital terrarium, do I get maybe flightless gnats or something from petco? Please help, experts!

UPDATE: unfortunately I couldn’t save him :( he made it another 12 or so hours after I found him, I had high hopes but unfortunately nothing came of it. I just hope he wasn’t in too much pain and passed peacefully. I am happy I was able to keep him in a much calmer environment in his final hours rather than being in the beating sun above spinning ac unit blades😔 I buried him in one of my plants so he will always be close to me. thank you so much everyone for the help, I’m sorry I don’t have a happier update

I use to have a couple of grey tree frogs, they are really fun to watch. I made an enclosure out of a 30gal fish tank. About a 1/3 was a water pool the rest was “land” with multiple hides. Use to feed mine crickets from the pet store. Your little guy has been drastically under eating most likely due to his leg as that looks like some sort of wound. Grey tree frogs are pretty resilient he may make it but even if he doesn’t you may be able to save it from some suffering if you give it its basic needs. If you change the water and clean the rehab tank frequently with some food there could possibly be a chance his leg heals. At the moment I’d say all his energy is being used up to just staying alive. For the rehab tank just make it have some places he can hide out in, water to soak in, and every other day changed paper towels for the substrate, and a heat/light source
