Looks like a Phalaenopsis miniature species, but which one? If you can id the bloom against the images on google, it might help a bit. Otherwise standard Phalaenopsis care. Maybe Phalaenopsis modest but that is a wild guess.

Oops, sorry for the omission, it’s Phalaenopsis (equestris fma. Alba x appendiculata fma. Alba). A primary cross of two species. What does fma. Mean? These are both alba species, how does the bloom come out purple and pink on white? Just looked up the appendiculata, it’s a real cutie! What I read that gave me pause was the need of 85% humidity. Yikes, can’t do that!

Whenever I move a phal it drops a leaf. I think they're just sensitive to a change in environment. Maybe you could keep a mister nearby and whenever you walk by mist the air around it? It probably needs high humidity because it is mounted.

Yes it is a Phalaenopsis hybrid. Registered name Phalaenopsis Tassanee Jongdamkerng.

Fma is short for form. How come Flowers are not white? Gene shuffling that occurs in most living things, example Red Hair inheritance in humans.

The door is closed on this room with a 600 litre heated fish tank. Humidity is 62%. Forget about the 85%. If your other Phals are happy, this one should be fine.
