I have had the tank running for a little over a month now. All of the water and live rock came from my 120 gal reef.
I have been in the hobby for about 6 years now and I do have a couple Anemones in my 120 gal reef, but I don't consider myself an expert on Anemones. So, if it just doesn't make sense to keep one in my 14g cube, then I just won't do it.
I could always see if my clowns would host a frogspawn, but ultimately would like to give them an anemone.
