I'll start by saying that about 80% of anemones in captivity DIE..NO JOKE,they don't do well at all in captivity.But there are a few things you can do to TRY to prevent it's demise.LIGHTING, Anemones REQUIRE(not need)but REQUIRErather intense "reef type" lighting to survive.This will keep the algae living inside the anemone alive.This algae is also what gives an anemone it's color,and also provide the anemone with needed nutrition.If an anemone looses it's color,it's a good sign that things are not going well...WATER CIRCULATION,They also need to be in a moderate water current.This current brings it food,and keeps it clean as it rushes by.. EXCELENT WATER CONDITIONS, This is why it is not a good idea to put one in a young,immature tank.They can NOT tollerate the poor water quality found in unstable tanks..FOOD,This is a gray area.Most will say that an anemone needs to be fed two or three times a week.I personally have NOT fed mine in over a year.That is NOT to say they don't eat.I occasionally come up a fish or two shy in my morning roll call.(one of the downfalls of owning one).The eat any meaty,FRESH seafood.Shrimp,Muscles,or other seafood that is cut into small enough pieces to be consumed.....Out of all of these I would say the most important is LIGHTING,and water quality...A few other signs of an ill/sick anemone are when it looses it's stinging ability.This sting is how it catches and holds it's food.To test this "sting" you can slowly reach into the tank,and touch it with the tip of your finger.When you touch it watch for it to "flinch"or jerk away.Also see if it sticks to your finger....If any of the three things I have mentioned are absent(color,sting,or movement)your anemone is in trouble...Because an anemone has a VERY slow matabalism,by the time we notice that they are in trouble,They are usually too far gone to do much to save them....Hope all this info helps.And good luck with your new invert....OH YEAH,They are an invert,,,So you must be carefull with any meds you are using...You can also add ZOE,by Kent marine directly to the tank water to help keep it healthy..Or soak it's food in it...
