I agree... If your test results indicate everything is ok and within acceptible ranges (NH3, NO2, NO3, PO4, pH, KH, etc.), you should be fine (from a water quality perspective / tank age at the time of addition at least).
There's no mention of your current lighting set up, tank size, or other equipment on your tank (flow likely being the only other aspect worth mentioning other than light in this case). Many zoas are adaptable to a wide range of lighing, but to truly give good advice, more info is needed.
