I guess the live stock selection must be those hardy type? Else temp fluctuation is one of the killer in tank.
yup, my tank max can keep 2-3 fishes but i have 4 because im doing weekly water changes, checking my water parameters regularly etc. if you want to have a successful reef, you need to know all about the reef chemistry. That's very important. As for the corals for now, yes, I have hardy type and soft corals. For more advanced corals you need advanced light technique all.
