Phalaenopsis questions from a newbie in the Philippines

[Zildjian]

Hello to all Orchid Board members,

Great to find this helpful forum which is good for a beginner like me. It's been a month now since I started buying orchids. I find it relaxing to watch specially their beautiful long lasting flowers. I first bought dendros as they are easily grown here then tried on Phalaenopsis. Last week I bought a phalaenopsis which I think is an old one with a keiki on the flower spike and the good thing is that there are two plants in the pot (total of 3 including the keiki). I bought it even w/o knowing what the color of the flower is because it's really a bargain at 150 pesos (~$3). Anyway, should I divide the two plants? When should the keiki be separated? Kindly help me decide.

Thanks so much in advance. Will post pics sooner.
