I bought a anemone for my clowns to host in. How long does it take for them to "Foot" themselves? I turned the powerheads off, hen they were on it floated around. Is there anything I need to do to help it foot? I dont know what kind it is but its white with purple dots on the ends of the tentacles. Funny note. My powerheads are off and my lawnmower blenny decided to make a new home in the Powerhead.
