First off, I'm sorry for your loss. Don't get discouraged! I'm no expert, but it sounds like there was a mineral in the tap water that killed your shrimp. A half gallon isn't a lot, so even trace amounts on your rock is a lot in comparison. If you're able, I'd run a parameter test on your jar before...

Your jar seems pretty open and I've heard that Opae like to have spaces to hide, particularly when mating. I think that giving them just that might help!
