polyps closed and won't open...

[petermai]

a good friend of mine gave me three different types of zoanthids. one of them is fine meaning all of the polyps are opened, while the other two, all are closed off except for one. my water parameter's good and lighting's at 216watts 50/50. i placed them half way up from the bottom of the tank. i don't know what's wrong with them, and also, the colony that does open up all the way...about half of them are opened up oddly meaning that they kinda droop down like an umbrella. any comments on this would be greatly appreciated. thanks.

216 watts of 50/50 is this pc or vho? What lighting conditions where they under? How long have you had them? How long did you aclimate them to your tank and how did you aclimate them? More than likely they are still getting use to your tank.

216 watts of 12k and actinic blue, they were under MH before. i've had them for about three days now. i took about an hour and a half to aclimate. i did so by keeping them in the ziploc bag that they came in and i clipped the bag to the side of the tank and add very little water into the bag slowly. so i'm hoping they're ok.
