I don't think they're the same. From what I've read about setting one up and seeing pictures of them you have to build a second level in the tank on a platform in order to have an aquarium section and a terrarium section.
I dont know much about paladariums other than they look really awesome.
My best and only advice is to look up DIY paladarium on google and see what you can find. It'll definitely take some research because they arent the most common thing around. But definitely would be a sweet idea!
