Ivery, it looks good! I can see two new leave (left side, near the top of the mount), so it is growing.
I was writing a blog post, and I learned that actually mine was a related species, A. asaroides. But the two species appear to come from Santa Catarina, and they probably share similar habitat. Also one literature said that they are from wet forest. So I might be wrong about keeping the root fairly dry, and they may be ok with pretty moist condition.
