Coral help

[royalstar]

Ok so ive got a Duncanopsamia and zooanthid for the tank. Both are only small.

My problem is that they dont seem to be opening. At times they are partially open, but then 30min later they will be completly closed.

Any ideas why?

Not long.. 5-6 days or so

How old is the tank? Temp? Salinity?
