I wouldn't worry too much about the leaning as long as his swimming has gotten better. He no longer rolls while he swims, right?
Did you remove the shrimp eventually? Shrimp goes bad ridiculously fast in tropical water, it's one of those foods that if it doesn't get eaten right away I scoop it out and throw it away.
Is that his primary diet? Because the other thing about shrimp is it's not very nutritious at all. I've heard it said shrimp is for fish like iceberg lettuce is to turtles, taken readily but not particularly good for them. When I have problem feeders and have to feed shrimp it's always stuffed with pellets to make sure the fish is getting a balanced diet.
As I said before do a water change(50%) you can even use your main tanks water to reduce stress on him and see how he's doing tomorrow. Hopefully by then he'll be a lot better and ready to eat and be reintroduced to your tank.
