My anemone has developed a black spot on it , dose anybody know why or what could be wrong with it?when it is open fully it looks worse.I have had it for about 5 mths

Could just be an accumulation of waste or dead zoox. I expect the nem to expel it within a few days.

Sorry, zoox means zooxanthellae which is the symbiotic algae that lives within the anemone. Sometimes when an anemone is acclimating to new environmental conditions, such as new lighting, it adjusts its zoox population by expelling some or allowing more to grow.
