dendrophylia question

[Goofyjas]

ANyone ever have any of these?
These have opened up during the day once or twice but I am trying to find out some more info on where to put them. They open up really nice at night but i am wondering what I need to do to keep them open during the day.

Mine doesnt open much in the daytime. Usually opens around 7:00 pm or when I start feeding. I feed each individual with brine shrimp or mysis shrimp cut up small.Ive had it for about 3 month now and it doing great... see my gallery for a pic

They should be placed under a ledge or some other dark area of the tank. And each polyp needs to be fed just like aquanaut said. They don't appreciate the light, that's why they won't open during the day.
