Once you decide which corals you like, and would like to have in your tank, post a question as to the needs or do some research. Even if you think they may be to difficult for you now, they may be easy as you get accustomed to keeping corals. Also, if you only like "softies", then you would't need to spend the extra money on MH
lighting. I would research as much as you can by looking at pictures, looking at online vendors pictures of corals, and decide which ones you want to have. Go from there. Aquarium Corals
is a great book to have if you are interested in corals. Hope this helps!
