Yes, they open and close all day long.
Several were open when I first replied to your post. The last feeding of the tank was 4hrs before that time.
The talk of spot feeding got me curious so I put some cyclops-eze in the tank. Several more sun polyps opened up after this feeding. I use the cyclops-eze as part of my frozen food mix. I wanted to see if the polyps would open up for this alone. I did not spot feed it to them, just put a small amount in the tank.
I think they can feed just fine by themselves and probably get more abuse when fed big chunks of food that fish or shrimp will try to steal from them.
Can you tell me how long it took you to grown them to a 60 polyp group. I might try spot feeding if it causes them to spread faster.
