Adding new fish???

I was wondering what is a good time to wait in between adding new fish? I was told to wait at least two weeks before adding new specimens. Is that long enough?

 

I try to usually wait a month between adding fish. Unless i find something i really want at the LFS, then its a different story :

 

It all depends on your tank setup and current stocking levels. If you have a dsb and lots of lr and your current bio load is low, then check your water quality. If your water is fine then why wait to get a fish you want. If you don't have a dsb & lots of lr then you might want to wait for 2 weeks.

 

what size tank and how long have you had it running? what type of filtration do you have on it?

and most importantly what type of fish do you want to add?

i like to wait about 2-3 week for fish. coral= like a day or two to see how they adjust.
