what all are you testing for, i find it hard to believe that in a month you completely cycled, and can add those fish(you may have cycled, but should not have those fish), even if you did finish your cycle, it should take months to stock like that, only add one or 2 fish every couple of weeks(3 or 4), so, what are you testin for,and what are your readings?, plus angels should not be added to a system until it is matured(several months)
what type of angel?
if you did not cycle, completely, the clown and goby may just survive, the tang is probably iffy(probably would not survive), but an angel, most probably wouldn't
as far as anemones go, i would nto reccomend them for any aquarium at all, especially a new one
