How long has the tank been running? Did you use live rock from an established system or store, dry rock, or a mix of both? Have you tested to be sure that your tank is cycling properly?
You're probably OK to add some easier/hardy corals, but I would take a little more time before adding more fish. Because you bought live rock and it's been a month you're probably in the clear. Wouldn't hurt to get a second opinion though
It's fully cured rock. I've had the fish in there for about a month at a guess here is what's in there.
