Bryan, the comment about this being an outdoor tree is correct. It is unlikely to ever adjust to living indoors. I couldn't see the soil surface to tell whether the pebbles were glued together. If they are, this also creates soil conditions no tree can adapt to. The problem is, the roots require both water and air in the soil, so the surface of the soil must be permeable, allowing both water and air into the soil.

It is hard to tell whether this tree can recover. Misting the needles will keep them green long after the tree has stopped functioning like a tree, with water being absorbed by the roots and being transported o the needles through the inner bark. It may have a shot if you move it outside and create proper soil conditions, which means fast draining soil with the surface permeable, watered regularly but not water-logged.

The good news is that this tree should be inexpensive to replace. It is not very far past the one-gallon nursery plant stage and youcan get a replacement for it this Spring, giving you the Winter to learn a little more about Bonsai, their care and development.
