Usually gnats are from soil staying wet, maybe due to your moss retaining too much water..I dig. Just got the same tree as a gift from the lady. Just a little home depot guy. Luckily I live in South Florida so light is not a big issue.
I seem to be getting some gnats in the Moss, that's the only issue. Neem oil seems to help a bit but I can't be sure yet.
Good luck on the tree, this might inspire me to trim mine down for some better shaping.
