Suggestions for preschool riparium?
I'm sure I could cross-reference a bunch of plants, but I'm hoping somebody has a link to a list somewhere of non-toxic plants for use in a rip/paludarium. Or maybe list a bunch that you know of (primarily common, please! - I'll be paying for this project from my own pocket). And I'll doublecheck anything anybody posts, so don't fear giving bad info.
I teach at a preschool, and it's a given that certain children will be putting pieces of these plants in their mouths. So it's obviously important that everything in there be 99.9% safe. Why 99.9? Because getting diarrhea after eating an entire plant is a natural consequence. And that's how we learn. But, please, nothing that could conceivably send a little person to the hospital.
Not sure how big, though I'm leaning toward a 20g high. I'm thinking 4-6" of water, with rocks and dirt, possibly MTS. Probably a mini-filter down in the corner on its side.
And that's how far I've gotten on it. I'll take any suggestions gratefully.
