It is a money tree. it is the only plant I can find to fit in my cage. I had gotten a nice ficus but it was too tall. So I found one like this. Is this safe? It is called Pachira aquatica
There is a search button at the top of the page - a search will show you quite a few threads covering the topic of the "money tree" _Pachira aquatica_. Here's one I posted; last post in thread
Short and to the point: Pachira is safe but unsuitable as it is too soft to support climbing animals.
