I got a couple of PMs asking about feeding suncorals, so here are more pictures. First the food: mini mysis and cyclop eeze thawing in a small bowl of tank water. The pipettes are those small ones that come with a refractometer, or perhaps you got some of those free ones from a club member (Doug, I think) some time back.
Once thawed, I turn off the return pump to my suncoral tank, and then squirt a small puff of food over each polyp every gently. I don't want the coral to retract, but rather catch the food. (Not unlike how we try feeding aiptasia so they'll injest the toxic meal we've offered.) Three pipettes worth of food is offered each night, so it really isn't a lot of food. It is target fed to avoid waste, keeping the food where it needs to go.
After 10 minutes, I may feed them again. You can feed them two or three times in a 15 minute period. However, if you feed them daily, once seems to be enough to not only do the job, as well as to encourage growth like I showed above.
Don't forget to turn the pumps back on.
Here's a small video of how I used to feed them latenights in my 55g: http://www.melevsreef.com/video/sun.wmv
If you have to do this in a tank with thieving shrimp, cut off the top of a 2-liter bottle and use that as a feeding dome. Press it down over the coral so that it sinks into the sandbed and stays in place. Squirt food through the top of the dome where the cap used to screw on.
I would suggest you drill a few holes through the dome to allow a little circulation in the dome just in case you forget to pull it off like I did once. I discovered I'd forgotten overnight, and the coral was very pale that next day. It healed up after a few days, but rather than risk that blunder again, I drilled some holes to allow some oxygen exchange.
