The best thing I found I could do with my greenies is give them a mossy habitat with different perches, a shallow pool, and keep them away from other animals. The moss keeps their tank wet, and they DO like to be with other toads so don't keep just one. Keep pairs or even groups.
They absorb moisture actually through their underbelly, so it's really important to always monitor the level of water in their tank. And those warts you see on their skin secrete a toxin that isn't too pleasant to people, but especially to animals. It can cause death in small pets, so make sure their tank is enclosed properly and a safe distance from access.
The toxin is sticky and can irritate your skin if you pick them up, so you'll want to wear gloves and be sure to always wash your skin before and after. Best to wash all the way up to your elbow, just to be on the safe side. You can transfer human germs, skin oils, lotions, etc onto them, and they can certainly pass salmonella and other fun stuff onto you.
I have a box of plastic service gloves I use, then throw them away after each single use and that works pretty well. But for the most part, they really shouldn't be handled all that much.
