What Biome should I use

[drm1217]

I have finished up the background and plumbing of my new aqua-terrarium, put I don't know what to plant in it!
Usually I pick a biome, like most of us do, to model my creations after of. A biome is like a desert or tropical rainforest. I want my aqua-terrarium to be a temperate biome. Not many people use temperate biomes, which is why I want to make one.
The animal I am building it for is either a red eft eastern newt or an adult eastern newt. More than likely it will be an adult eastern newt. Adult eastern newts are found around muddy lake marshes. If I chose that ecosystem, then I would on the land portion I would mostly have to use grasses in partially submerged sand and a little soil. My other idea is to have a temperate forest with a river going through it. This would appeal more to a red eft. The plants planted there would be ferns and maybe, if I could find one, a pine bonsai. I would also include temperate moss. This choice would have more hides, but the plants would be harder to find because most plants in a forest grow large (that I know of)
If any one has any ideas for what I could base more tank after of, or what other plants I could use, I would be very grateful!
