I purchased and acclimated a RBTA from a local reefer last week and so far all is going well. My only powerhead in my 28 gallon NC is a Vortech MP10. For those who are familiar it comes with a foam cover that covers the intake portion of the powerhead. To be safe I covered the whole thing with filterfloss and a rubberband. Is this going a bit overboard or is it possible for the anemone to move into the outlet of the pumps fan? Should I just use the foam cover supplied that covers the intake portion?
