I have two of this type. and i was at a stand still with this tree.. It was one of the b.s bonsai at home depot. So i cut more then half of it at the botoom and repotted the top that i want. There is a pretty good arial root at the top with a very developed root ball atached. That i repoted with the remaning trunk. will it survive??

I set the pot in a fish tank with some other ficus projects to keep up the humidity, under a flouro lamp. is there any thing elese i should do to insure survival? Because now i actualy like the thing.
