Hi, I've had a Leather Coral (think Sinularia notanda) for about a month now. All my water paremeters are ok--haven't tested fro calcium and alkalinity yet--just got those kits. Ammonia and nitrites 0 and nitrates <5ppm. Ph steady at 8.2 and salinity 1.024.
It's a 29GBiocube, live rock and sand. 2 Clarkii Clownfish and a Royal Gramma. 2 Turbo snails and 4 hermit crabs.
I've noticed an area of brown discoloration toward the base which seems to be moving steadily upward and did catch a Hermit chewing at the base or the algae; couldn't quite tell. Part of it would also get kind of limp during the day. I tried moving it into an area with more flow and more up on rock. It just completely laid flat. It closes up at night and opens up when the lights are on. Polyps allopen. I feed Rod's Original a couple of times/ week and turn off the pump.
Is there anything I can do for it?
Thanks for any help!

In this pic, I know it is too close to the Green Hairy Mushroom, but it flopped that way. I thought it would lean on the rock, the same direction it had been leaning before when I had it up on the rock.
