I agree 100%. I did not catch that for some reason. Anemones almost never do well is tanks that are not well established. I thought it said 6 months, not 6 weeks. That being said I would suggest you return it to the LFS or give it to someone with an established tank to care for until your tank is at least 3 months old, preferably 6 months old.I think a six week old tank is a bit too new for them. They do seem to be happier in an established tank (IME anyway).
