Coral Ideas

[votek]

I have Coral Life 10,000k 20w lighting on my 20g tank. In the future, as in a month or so from now, I would like to try and do some coral.

I realize they can be very touchy to water conditions and if something goes wrong, even just a little bit, it could kill the coral. However, I do want to give it a shot and try to maintain it as best as possible.

What corals do you suggest I consider for the tank?
What preperations should I make for them?

Thanks. :)
