How do you get an anemone to attach in your tanks? I added a beautiful sebae on Thursday and put it on the opposite end of my tank from my mp40 in a 75 gallon. I turned down the mp40 to 50% or so and placed in the sand near some rocks. It looked very healthy with sticky tentacles and a closed mouth. My clowns were even in it. This morning, it was chewed up in my mp40. What gives?
