30 gallon paludarium tips?
ok, I want to create a simple paludarium type tank. I want to create an Amazon streambed theme. where water is like 75% and 25% land. I want the substrate to slowly rise to a hill in one side as the water level decreases as if it is the edge of the river. however, I have some concerns regarding too much weight on the land side. Just a suggestion, but would it work if I add a block of Styrofoam, and then put the substrate over it? This would make the hill higher, and not as heavy. would the styrofoam be ok if I weight it down with the sand? Are there any things I would have to do to the styrofoam to keep it ok and ready to use?
would I have to put something between the water and the land to keep the water from coming on the land part? or will the water not come to the land part at all?
my substrate is a mix of silica sand, with a little soil, and some gravel.
Are there any plants that you would recommend for both water and land?
