Marine velvet outbreak

[ifwisheswerefishes]

I have finished treating my display tank from marine velvet. It was really bad. Many survived however plus my corals too. So how long should I wait to purchase new fish after a marine velvet outbreak? 2 months?
I was thinking of starting with some green chromis, and if that goes well then adding a Midas Blenny.
125 gallon soft coral reef with sump.
currently have a hippo tang, sailfin tang, flame back angel, 2 orange firefish,yellow head sleeper goby, & snowflake clownfish.
Thanks in advance!
