RBTA closed during the day, open at night.

[CallMeJus]

44 Gal Mixed Reef, two adult Occelaris host him, and an Anemone crab. The Nem used to be open and beautiful during the day, now he stays closed during the day and opens at night. Still has great coloration and looks healthy though. I was target feeding a silverside every few days and he would gobble it up. Now doesn't seem to want food, and the other tank inhabitants seize that opportunity.

Any ideas? Thanks

How old us your rank?
How long has the nem been in this tank?
How long since the change in behavior?
You make any recent lighting of flow changes?
What's nitrate and phosohate level?
Reccomend you know mag level, too high snails die, too low, Slow Stoney coral growth.

If you could provide the members some of this info that would help.
