would take some time for them to be comfortable in your water to really open up big.. unless u don't have good quality water.....

Dont worry, mine was not opening till 1 month later when undisturbed and suddenly all started opening.........

check for worms burrowing thru it... I have a huge woorm burrow thru mine few weeks ago... desecrated it....

Check you water parameter. My star polyps refuse to open in my 2 footer when it was infested by cyno! Phosphate level was high then. Even though I clean away the red slimy algae on it and still it refuse to open.

Since then I transfer to my new tank.....they started opening in the 2nd day! I strongly believe its the water quality! Be careful with your rest of your LS!

I have checked the NO3 is ok, but i think I need to check the PH. Thanks for helping! I noticed some has open oredi!
