I would like to keep a 2 or 3 small fish and some low light corals. I currently have 2 freshwater tanks but Im totally new to saltwater fish tanks. I would really appreciate to get some advice from you guys. I think there are some very knowledgeable people on this site.

Looking forward to receiving advice from you guys.
