Question on zoas only tank

[Oilers]

I have been collecting zoas frags from various sources and I am thinking of setting up a tank that will house only zoas but have no idea where to start. I know that there are a few canreefers out there that are experts in this field. Any suggestions/tips would be greatly appreciated.
1) What is the minimum size of tank I would need? Would a nano tank work? What would consider to be the ideal tank dimension for zoas? Tall, short, wide?
2) What is the best lighting for zoas? MH? T5? LED??
If you can think of anything else, please feel free to post them.
