We have a goldflake (1.5 years), blueface (2.5 years), regal (2.5 years), flame (3.5 years) angel as well as a moorish idol (1.5 years) in an SPS dominant reef. No issues with SPS, euphylia or leathers but the few zoas we had in the tank disappeared in the first few months. I would not advise in a mixed reef (or you will end up with SPS dominant :-). We have another tank that is a mixed reef that has only reef safe fish in it but my wife loves the angels & MI so we designed this tank around the fish in terms of coral inhabitants.
