Help with Chocolate Drop 'Volcano Queen'

[KongFuzi]

Hi Everyone,

I'm new to the forum and to growing orchids. I bought two of these plants in the gift shop at the hospital where I work. One of them had great smelling blooms that sadly died off. They seem to be doing OK, but the one that bloomed has already lost two leaves and I want to prevent any further damage to these great plants. So...looking to learn more about the plants and keep them alive. Thanks.
