Agreed, takes some time but you can train your coral. Most of my LPS actually open up nice and big as soon as I turn the pumps off. My Aussie acan even opens up as soon as I stick my hands in the tank. Just keep target feeding it and eventually you can get the polyps open during the day. If all else fails buy a Rhyzo!
