Brassias have about the same needs as Oncidiums. They do best in moderate light and will sometimes get spots on the leaves if the light is too bright. They need more light than phals, but still do well in the home. You made a great addition to your collection.
I added a mini cattleya to my collection at the last OSO orchid auction. I will take a photo of it and post it soon. It is growing in a wooden basket and is out of control. I just love it!
