Mold in Tank?

[mpiggy]

Help. New Orchid Tank, set up for a 6 weeks, because I wanted a masdie.

Although I've have kept orchids alive for years (and a few occasionally bloom) I feel like I'm a newbie. Never had a major pest problem but have read about them.

So now that I've found these white specks on the terrarium and on some leaves, I'm freaking. Is this regular mold? Can I sigh in relief that they aren't signs of mealy bugs - or is this just as bad?

What do I do about this?

Appreciate any comments or suggestions.
