Adding fish after Corals

[Rmorrison23]

Hey reefers,
Someone at one of my LFS was telling me that I should have all the fish I'm ever going to own before putting any designer or "expensive" corals in my tank.
Does anyone have info on this? They claim that the small bacteria swing or additional ammonia(all be it for a very short time) could kill corals. I have seen countless refers add fish later in a tanks life so I'm just wanting to verify this or not...seems crazy to not be able to get more fish after you have got some nice corals.

Thanks for the help!

I ran a coral only tank a year, and still have no fish. Unless you have something extremely sensitive, you’re filtration and water changed should take care of it. You should have no problems adding fish.

That's what I figured but wanted to confirm...obviously I'm not going to add like 10 fish at once lol
