Thank you guys for the suggestions. I currently work at an aquarium store and have for the past 5 years so I've got access to hundreds of FW plant species, however being that it's a saltwater plaudarium none of those would work. I do plan on adding mangroves and a number of macro algae species soon but since they're a semi-submersible plant they will go in the sloped plane on the right side of the tank. For the background I may stick to succulents since they seem to be the best option as far as survivability but don't really go with the theme of the tank. And I live in central Indiana at the moment so unfortunately no oceanside access. Thank you all for the suggestions.
