Okay, so I had an idea that would be pretty cheap and it would make a pretty piece for my room. Basically what it would be is a 10 gallon fish tank paludarium. It would have a mound of sphagnum going around on all sides and a big puddle in the middle. The puddle would go about 1/3 of the way up the tank and the sphagnum would go up about 1/2 the way. I would put live sphagnum (I have boatloads since my cultures grew) all the way around on the mound of dead sphagnum. In the bottom of the water would be a thin layer of sand. I may also have sand going around the sides up to where the water meets the air. I have everything I need to do all of that on hand. Another option of layout would be to make the left side of the tank land and the right side water, so then I could stick a hang-on-back aquarium filter on the side and have the water sucked up and waterfalled back in, but that would be noisy. Suggestions?
What I need help with is picking one or two (two max) Nepenthes to put in the tank. I guess the requirement would be a shallow root system so they don't drown themselves. So maybe a bog Nepenthes. The other thing is that the plant needs to be able to cope with 60s-70s in the night and 70s-80s in the day -- the lower end of the given during winter and the higher end during summer. Maybe something that would grow more slowly OR something that starts vining super quick so I can make it go everywhere around the terrarium.
Any suggestions? I'll find out what kind of water plants can be half-submerged that are good for paludariums and I'll stick them in the water. I'll also have to pick up a glass hood to put over the tank so I can set the light on there and keep the humidity in.
