Hi Renee,
I keep red eyed tree frogs ( no toads- so I am not sure what is safe -specifically for them). The pothos is very sturdy, as you know , commonly used.
Below is a link to my "Set Up" Album if you would like to take a peak.
There is information in the description for each plant.
All of the plants listed have been in my enclosure for many months and are doing well w/ out needing hours of care.
AND, my personal rule - they are going well in tropical soil.
( w/ the exception of the artillery plant- I purchased it recently for soil cover but having a little trouble getting it established)
There are some plants listed her that are a bit fragile. But, I like the variety, as I enjoy the plant care as well as my frogs!

Note: Take care to prepare the plant properly before putting it into your enclosure! Lots of threads regarding this- easy to fund on FF.
Enjoy creating your new set-up!
