I was told they feed at night on the crap floating in your tank from stirring up the sand bed.

Is it necessary to stir my sand bed in order for them to stay alive, grow, and be happy?
Who told you this?!? Never take advice from them again! Stirring up your sand bed is one of the worst things you can do to your tank. Stop doing it. You're going to throw all your water parameters off and you'll get diatoms because you're sending your tank into a mini cycle.
Anyways, as for feeding an acan:
Mine love mysis. I use two options to feed (both usually need to be done at night unless your acans tentacles come out during the day as well. Mine know when they're being fed so they do, most don't, some can be trained, others can not)
1) while I'm feeding my fish, I'll shoot a little fish food their way with a turkey baster
2) at night, once the tentacles are fully extended, I use forceps and place mysis shrimp directly into the center, wait a few seconds the the feeder tentacles will latch onto the shrimp.
As Kraylen said, if they're in high flow, you're going to want to turn off the flow or lower it. I always lower flow for about ten minutes while I feed my corals.
Also, if you have fish/inverts (especially cleaner shrimp) that are complete pigs like I do, you may want to stick around and chase off the fish. My Sailfin tang will rip out every mysis if I walk away from the tank. The Acans need a little bit to fully engulf certain foods (like a chunk of mysis).
