This is Phalaenopsis Braceana
And this is Aerengis Brachycarpa. Both are still young seedlings so it will take a couple of years before they might flower. According to the person who grew these from seeds these have a chance in the low light levels of the vivarium.
I think this is a Oncidium 'Twinkle' which I won in the raffles. It wasn't the Cattleya I had my eye on but nevertheless it makes a nice houseplant to cheer up the living room during this grey January.
