two weeks is really not long at all , smartest thing to do is let the cycle run its course then get a clean up crew,then you can think about adding fish.personally i would buy a small damsel they are quite hardy and leave him in there for a couple months then think about adding small fish ..SLOWLY!!. then you can pass the damsel on to another person starting a new tank or just keep him although they are little bastards to remove and keep lol.your clowns are showing stress because of the cycle,move,new food, new lighting etc. another important thing is to start up a hospital/quartine tank then you could add fish there first then treat them if need be without any harm to your display/main system, just about everyone starts a tank without doing this and they pay for it down the road.practise and follow all the guidelines because they are their for a reason ,to help you start a tank without having to pay for unesscesary things. hope this helps
try to include more info when posting with fish questions like water parameters, tank size ,tank age,livestock etc.
