I just started restocking after letting the tank sit fallow with corals and the few fish I had left from the die off. At least a two months or a little more, added 3 more pajama cardinals, I have 5 pajamas and the one blue hippo tang. Been about a week or two now with no issues. I order 5 designer clowns from a friend that breeds them. He put them in his QT tank for me. Picking those up Oct 5th. Its always good to have a friend that has a QT tank to use if you don't have one.
