Ok, i have just cleared my fbt tank. It was originally half water, half land, but without a divider, which i need to get. Now, here are the questions:

1. What can i use as a divider and how can i keep it in place. What material should i use?
2. My tank is 45x45x45cm, can i house any more frogs (i have two in already)
3. I am going to be planting plants in the tank, but i want them to look exotic. Ive already got a creeping fig, but i would like more plants that look nicer than that. Ive researched good plants to go with fbts but they all look quite boring, so if anyone can suggest any good plants, that would be well appreciated. Bare in mind i live in the UK.
4. Im thinking of using abg mix, as this is good for plants. Underneath I'm putting gravel as the drainage substrate, but i don't know how to remove water from it when its full. Also, what type of mesh should i use to separate the soil and gravel.
5. As I'm getting more (hopefully) exotic plants, what light should i use. I want it to be cheap but good (preferably not over 20 pounds).
6. How will i clean the substrate? Ive heard springtails are good for this but im not allowed to get them lol.

any pics of your setups and explanations about how you did them would be great! Thanks for helping
