Coral = reef.
It's really pretty simple.... Put warm salt water in a glass box with a light over it and some pumps to move it around, add live rock, wait a few weeks, add some crawly things.
The more current and the more light the better. Aim for a temp in the high 70's, a pH in the mid 8's, and wait for your ammonia and nitrite to settle to 0.
Do weekly water changes of 20% or so with distilled or RO water.
I know I sound like I'm being silly... but that's really the cliff's notes version of what I did.
