It is a ginseng ficus. It is a good plant for indoor bonsai, being a tropical evergreen.

It is not a tree that lends itself to traditional bonsai styling very well. Most of the ginseng ficus bonsai examples I see, just make a feature of those roots and leave the rest fairly shapless, just grown out full and tight to hide the trunk chop.
The ginseng ficus bonsais that attempt traditional styling with trunk movement and foliage pads, etc., to me look tortured and unnatural:

The only ginseng ficus bonsai I have seen that I really like have been cascade style:

But understand I am the farthest thing from a bonsai expert and when you get to questions about style, I am giving you nothing but my personal opinion. My recommendation at this point since you just got your tree and you are new to bonsai, would be to do nothing, but learn to take care of your tree, keep it alive and healthy and get to know it. Next year is plenty of time to do anything about styling. And cascade is a very technical style, that requires knowing what you are doing and years to develop, since it is so opposed to what the tree "wants" to do.
