    According to the Reef experts in Norway it cant be a Red Planet because ORA doesnt ship to Norway. Could there be any other coral that has this type of colouration and not be a red planet?..... Thanks Dean

    Ritteri Amenone and flat tentacles

    Just a final update..... After 2 days the anemone was looking very well settled, so I fed it some silverside and it ate it immediately. I also introduced my clowns back in the tank a day after that. It hasnt moved and is loving its spot in the waveflow and close to my light.
