do they open before you feed when the pumps are off or during the feeding process? not to sure but i know that when i turn my pumps off my fish dart to the surface but i wasnt to sure that sun coral had the same feelings. maybe someone else can chime in
Mine starts to open at the same time every night, right before feeding time, while the pumps are still on. I was told by the staff at Preuss that it would learn my feeding schedule and start opening then or just before.
This colony opens ~ the same time each night, but ALWAYS seems to be triggered by the water movement stopping... feeding only begins when the water movement has stopped. I have noticed too that they are open AT night, or rather - early in the morning, when the tank is still dark, and the morning sun hasn't reached them yet...
