I am setting up a 315 gal reef. I currently have a pair of true percs, 2 small blue devil damsels, and 6 fire gobys. Can I put in some small tangs, some dwarf angels, and some wrasses? Will the tangs and the angels get along? I know that I need to put all the tangs in at the same time and all the angels in at the same time, but do I need to try and place all the tangs & angels at the same time? I dont want to over do it!! Thanks in advance for the advise......
