Also read a post up above yours it said plants eat waste of the frogs product. Here are some clarifications of that. It takes 2-3 days for the waste to be broken down into harmless soil by the plants. So if you have a lean mean pooping machine you may want to get more plants. As well as if your frog doesnt poop much you might want to have less plants or feed your plants on some other way. Remember not to use chemicals or pesticides though.

Also if your frog/toad is a burrower remember to keep the plants potted and in place with rocks to prevent any digging and demolition of your plants. Also if you go for plants you need to get a plant light. If not just buy a uvb/uva light that has a low wattage(40-50watts) it depends on the height by the way. Just make sure its not going to bother the frog/toad. Keep the light on for a photo period of 12 hours or so a day. This will stimulate the frogs behaviour and all. They sell light timers at some petstoresand hardware stores. Make it so the light turns on around 7 or 8am and turns offf around at most 9pm.
