I have never kept frogs or had a paludarium, but I am thinking of starting a one with green tree frogs, and I had several questions. The tank that I'm eyeing is a 15 gallon column (about 13x13x24). The setup I'm imagining involves a large piece of manzanita driftwood like this one Natural Red Manzanita Branches, 24" tall- Blooms and Branches. The bottom 8 inches or so of the tank will have the stem of the driftwood submerged and will have red cherry shrimp and aquatic plants. The top branches are frog territory, and will have some plants as well.


My questions:
How many frogs could I keep in this setup? I am hoping for 2. If this is too small, I can look into getting a bigger tank but I don't have much room.
Will the frogs drown if there is an 8 inch deep section of water at the bottom?
How would I go about making a sort of land section, like the ground around the tree? This way the frogs would have more places to go instead of just clinging to branches 24/7.
Are these frogs noisy at night?
Is there anything else I should know?


Thanks!
