I feel I should warn you about kenya trees. Most hobbyists who have kenya trees would be happy to have you come and take them out of their tanks. They fragment and once embedded in your live rock are very difficult to get rid of. Along with zenia's, yellow polyps, gsp's, anthelia's they can all overrun a tank in less than a year. The zoa rock I would say run's about twenty to thirty locally for something with that variety and size.
