I can't tell if your anemone is dead from pic's but if it is it will have a horrible smell and needs to be taken out IMMEDIATLEY and carefully with a siphon..if you try to scoop it out or pick it up it will fall apart and the toxins will kill your fish..My roomate accidentally did this and we lost everything..even our hermit crabs and the bristol worms from the live rock died from the toxins..good luck!
