Figs are mostly tropical plants, naturally growing wild in south-east Asian jungles. Many hundreds of species make up this large tree family. The tiny flowers are completely enclosed in the developing fruits which are borne in the leaf axils and are produced each year. You may find that as a bonsai, however, fruiting is not very common.
Most rainforest figs produce aerial roots from the branches and trunk.
Whether to leave these on or not and incorporate them into the design is a controversial issue for bonsai enthusiasts, although it does matter on the overall design of the tree. The roots are brittle at first, but strengthen and turn into a very strong part of the tree once they reach nutrients. While ficus are voracious feeders, they are very forgiving and can go a couple of days without watering, so water them sparingly to make sure you do not cause the root system to rot. To reduce the leaf size, defoliating, especially towards the end of summer, is the way to go. You must be sure to remove the growing tip or sheath when you do this however.
