75 gallon Australia Paludarium/Vivarium

[daybr4ke]

Hi! I'll soon be acquiring a used 75 gallon tall tank with some WTFs I am rehousing for someone. It's going to need a little cleaning, but after that I want to put in an almost fully australian planted living vivarium. I love the idea of housing a frog with the plants they would encounter in nature. Larry Wardog's 55 gallon tropical Forest Paludarium is absolutely beautiful, and an Australian paludarium or vivarium was his idea initially. Here's a link to that thread:

I'm going to start with the plant list.
1. Ficus Benjamina-The weeping fig is an Australian native. Ficus microcarpa is an alternative, also australian.
2. Schefflera Arboricola-The Dwarf Umbrella tree may not be native to Australia, but it looks like a smaller version of a larger plant which is native to Australia. Not sure I have room for this.
3. Epipremnum Aureum- The humble pothos is naturalized across Australia(and New Guinea), and is a good option as a naturalized species.
4.Epipremnum Pinnatum- Cebu Blue Pothos is an Australian native, a relative of Golden etc pothos. I am searching like some sort of plant fiend for it.
5. Chlorophytum Comosum-Spider plant. While not a native of Australia, in the same genus is C. Laxum, AKA Bichetii Grass, which looks almost the same as normal spider grass. Spider grass should make a good stand in.
6. Austral Gem fern-Hybrid Australian fern. One of the species it is bred from is from an island off the coast of Australia and the other is native. Native enough for me.
7. Dendrobium Kingianum-An Orchid Native to Australia. Not sure I wanna use it yet. Havent worked with orchids.
8.Codiaeum variegatum-Gold Dust Croton. My gf wanted me to get it because she thought it was pretty. Looked it up and it's native to Australia.
In addition to these I want to add another australian fern. I'm still working out what will make it to the final version. Any experiences with these plants would be useful as would recommendations on the additional ferns(preferring hardier ferns. Austral Gem is pretty sturdy.)
Layout-wise I'm planning to have the ficus as a centerpiece in the middle to give it growing room, with the other plants distributed around it.

Thanks for reading!
