Med. flow is correct. As mentioned, they do not like to be blasted with flow. As with all new corals, finding the correct placement in your tank can become a trial and error persuit. IF it does not seem to be happy where you have it, try another spot. When provided with the proper placement and water parameters, this can be a very fast growing coral. I am able to frag 6-8 heads every six months from my mother colony. Not too bad when I sell them for $10/head.
Some people are like slinkies...they serve no real purpose yet can still bring a smile to your face when you push them down the stairs!:p
Have a great day! Brian
