Before you add fish I assume that your cycle is complete? What are your test parameters? I would siphon any remaining gunk (of what was a shrimp as it should have rotted away) and do a good water change (even up to 40 to 50%) to help eliminate any nitrate buildup.
After the water change let the tank set a day retest and then go pick out fish.
