Is there any way to stop anemone from moving to the power head suction part? I don't know why but they like to go there. BTW why my anemone tip is turning red? Its actually white in colour. And I have a clarkii clown and maroon clown in my tank, they fought for 1st day when I just place in the clarkii, but now its gradually decrease, so my question is, if I were to place in one more anemone (the one before is with the maroon), would the maroon take both two? Because I want the clarkii to have one for its own.
