Coral Question For Biocube 29

[biocuber]

I am setting up a biocube 29 and want to create a lush coral reef look. I have never kept corals before so I want to start with a couple of easy types that will grow fast and spread across the live rocks. The lights are the standard coralife 36 watt 10000K and 36watt actinic. Any suggestions would be appreciated.
