Favities - sweeping tentacles ?

Where did you hear this;

"I have heard they could benefit from feeding zooplankton
during night - they hunt plankton with sweeping tentacles"

Looks like I made old mistake of listening to wrong people :-)
I am new to SPS and instead of reading stuff in a reputable
sources I trusted one of my "all-knowing" friends who has
reef for 5, maybe 7 years :-) When do I learn not to do it ? ;-)

I have heard and seen statements similar to his but just assume
that don't understand the real deal about sweepers and are
just assuming they are lookin' for food

The thing is I tried to feed my favities and they do not accept
zooplankton... How can I stimulate them to eating ? What food ?

Sweepers are for defense, fighting and attacking other corals. Why would there be a need
for sweepers to do this, when the regular ever day tentacles do this ? They are not out
as they sense no near-by threat to be out. They also are not structured right to catch
food. It is like you trying to catch a fly with your hand while your whole body is covered
with sticky fly-paper :-)

I see... sometimes, when I feed my hermits with some pellets
some of them land on the coral and stick to it... I am not
sure if coral can benefit from this kind of food, can it ?
