Just bought this bonsai yesterday but dont knowyet how to tell what kind of species it is...
This is the easiest species to identify.
Please take off the fake moss, make sure the pebbles are not glued together, see if the real soil it is planted on is a draining substrate.
You can identify your plant by clicking on the link above , in the menu bar.
Good luck and keep it alive, it needs plenty of water AND natural light.
