After your initial cycle and bacteria boom there are no other "cycles" per say, just the tank maturing over time. You local LFS
is correct and a year is about the right time for an anemone. I didnt listen and got one after 4months, I have been lucky so far, but I also watched my parameters before adding it to my tank. My parameters have always been ideal, in my 46 gallon and now in my 112. Good water quality always helps.
For now I would get a good size frog spawn for about $40. Very easy to keep, pretty to look at and your clowns will take to it as well. My clowns go back and forth between my frog spawn and my anemone.
