Hi - I have not had good luck with the 3 cuttles that I got from a lfs. I am heart broken The only thing I am wondering about is the two tube anemones I have in there. I've heard that those nematocysts can float around... but two of my doomed cuttles were almost dead in the bag when I got home. I've a 125G with a lot of carbon and good skimming, cool (72 degrees), subdued lighting, slow current. Now if only I had a couple cuttles, my life would be perfect!
