Hi,
Welcome! One of the best things you can do as a reefkeeper is to constantly learn about the animals under your care. This website is a great resource but ideally, you should draw from many other sources. Some really great reef books have come out in the past few years. More than any other source, they can provide the kind of depth and scope that will be very helpful as you begin reefkeeping. Listed below are some really great books, most of which should be available through your public library or from the BRS' own library (which you'll have access to if you join as a full member).
1. Corals: by E. Borneman
2. Reef Invertebrates: by Calfo and Fenner
3. The Reef Aquarium Series: by Delbeek and Sprung
4. The New Marine Aquarium: By Paletta
5. Natural Reef Aquariums: By Tullock
Good luck and welcome!
