Wah, tonight? Read that u feed your suns in the middle of the night. At that time, i'll proberbly be asleep and my tanks lights off. Haha, i just fed 3 cubes of brine shrimps for my suns...wonder if they are full. Will increase it to 5 cubes tomorrow. What i do is pour in some marine snow/aquaz phytoplanton to make the suns open up abit first and then feed them. Its lots of work, but the satisfaction of seeing them opened up and greeting me with those huge polyps are definately worth it!
