Save me the "wear gloves, doofus" advice... I've learned my lesson.
The tip of my thumb where I (might) have touched a Zoa (tub's blues, if it matters) is slightly tingly. I think it felt like that within a few minutes. No open wounds. I don't know whether it is placebo/overthinking/overreacting or if I've got a hospital visit in my near future. Any thoughts, experiences? Please lend me some wisdom here as I'm kinda freaking out.
WEAR GLOVES! 
You'll live I think.
don't suck your thumb when you go to sleep tonight 
Just ensure you properly clean and scrub your hands
Regular zoos aren't that bad as long as you don't have
True Palythoas which can do major damage
Sounds to me like you got stuck by a bristle worm.
I'm still alive and by all indications if it was Palytoxin, I'd be good and dead by now. Probably just a bristleworm or some allergic reaction, but it did stress me out there for a few minutes (mostly the thought of a bill for an ER visit).
Well, the bill is incomparable to the price of your life. If conditions are not improving, might as well get it checked out.
I dunno, some ER's are prettttttty expensive 
Zoa's can be just as deadly. Peoples sensitivities to the palytoxin differ. Most worst cases have been with epizoanthids and they are reported as being the least worry.
I've never had any problems, but everyone is different, you could be allergic/sensitive to something.
