It's okay, don't panic. Bloat is simple, and there are a couple things you can do. First, fast him for a day or two to see if that helps him out at all. If he is bloated, he doesn't need anymore food going in. Second, you can try getting him to flare. I don't know why, but they often poop when they flare, which will help matters. Third, if you are really worried and Patriot remains bloated for a couple days, you can try using an epsom salt treatment. 1 tsp. per gallon, premix it with a bit of tank water so it is completely dissolved before you put it in there. But the first thing I would try would be just fasting him for a day or two.
It might be worth it to try getting him a bit more varied diet. Pellets can be good if they are a good brand... I don't think he will get all the necessary nutrition from the shrimp alone.
