Female died day before yesterday, male is still alive and obviously trying to fight it. And yes, both are adults.
I'll try to answer all the questions posted, sorry if I missed anything.
We've gone over everything that's been done in the last couple months, and the only change in anything (including food) has been their location. They were moved to the other side of the house, away from the windows, because it was getting cold. All the snakes were moved to the same area, because it's a space that's easier to regulate the temperature. That was it. Otherwise, no cleaning products are used near the snake tanks, their tanks are cleaned with safe products. Their water is the same water everyone else gets (all our reptiles, bugs and arachnids). This is why we are so confused, nothing has happened recently. I'm just confused and have no idea how to keep this from happening again.

Sorry to hear about the female. It's certainly an odd scenario and not one I'd like to find myself in.

I would treat them like they were highly contagious... If there was some sort of toxin in the surroundings or water, I'd expect the inverts to be the first to react to it. The muscle contractions that cause star-gazing behavior can be caused by anything that advances to a serious point (I've heard of snakes doing it with severe RI's before). If you can't take a body to the vet to get an autopsy you probably won't figure out the exact culprit. Best thing to do it just try to isolate any equipment that could have in contact with them and keep it away from the others, especially if you've got other native colubrids.

That's a really weird situation... Could be something was going through the wild population and maybe the sick one passed it to the other two and they just started to be symptomatic? The one that died from this previously was w/c too right?
