Welcome to the forum!
He is very likely going to recover! He has bloat. All you really have to do is not feed him for a couple days and it should resolve itself. Getting him to flare can help him poop and, if you want to aid in speeding up the process, you can add 1/2 teaspoon of unscented/plain Epsom salt per gallon of tank water. You can find it in the laxative or first aid section of Walmart or other drug store.
Since it happened so quickly I suspect he may be prone to bloat. You can decrease the likelihood of it happening when you feed him by soaking his food before feeding.
Good luck!
