Further to my last,
Since you’re going all out with a bio active setup, you might do a locale specific design, incorporating various favourite haunts from your cham’s native land. Veiled’s, for instance, have a distinct proclivity for thorny legumes such as acacia. While it may be difficult to find an acacia bonsai, as legumes, they are extremely fast growers and you can probably have a two foot specimen within a year. Other plants similar to acacia are Brazilian raintree, mimosa, albizia julibrissin. If you’re a Furcifer lover, Madagascar is home to some show stopping flowering trees, many of which are very fast growing and can be used for both bonsai and chams; so again, growing from seed need not be a lifetime affair. You’ll have to double check toxicity on anything you put in there, but that’s no big deal.
