So when my 29 Biocube is over a year old (it's 7 months now) I planned on adding coral. I have seen other people's nanos with amazing pieces of beginner coral and I thought now would be a good time to plan ahead. I know the basic requirements but I have some questions. The Questions: 1.What are good types of coral for a nano tank? 2. Do they need to be specially fed and supplemented and when? (It's a dumb question, I know) 3. Is a calcium reactor or automatic topoff needed for a nano? 4. Is a refugium needed for a nano? 5. What are some tips and pointers to keeping coral in a nano?
