90x45x90 Exo terra paludarium. I have questions

[whim]

I cant seem to take a good photo. It looks better in real life I swear.


My questions are:

What orchid is this with the yellow flower? it was sold as Lepanthopsis astrophora x peniculus, but it doesn't look like it.. unless it has a virus or something?

Is it okay for moss to overgrow the orchids? if not, how do I stop the moss out-competing them and suffocating? its really hard to manually remove without ripping the roots.

cheers!
