I have a 240 gallon reef tank that has been cycled for 6 months. I currently have 2 clowns and 2 anthias in there. My questions are I want to add 2 yellow tangs, 1 hippo tang and a Naso that I have in my 75 gallon tank. Can I or should I add them all at once? Should I go slow with a couple here and there? If so, what order?

heard its better to have them in odd numbers.
