Oh I totally agree. I knew they were very bad stingers, I just did not know they had long sweepers. Mine just always looks really fuzzy, like it has thousands of polyps and then once in a while they get what I thought was really long at about 1/2"...I can't imagine 2-3". That would look so cool though.

I have a fairly large Hydno and the sweepers are probably about 1.5 to 2 inches long. They almost always are out at night but once in a while they are out during the day. Helluva a sting; stung the crap out of a digi that I had too close.

Do they come out every night?

I wonder if mine is just not happy.

Mine don't seem to come out every night; in fact, they don't come out that often; unless it is very late and I'm not seeing them.

Mine swells like a balloon at night,the only time I've noticed sweepers is when it was agrivated. Maybe its a defense mechinisim,just guessing here.
It sure is purdy though lol

In my experience they usually only extend when there is something nearby it wants to eat. I had an acro beside one for months (about 2-3") and then out of nowhere one day it looked like a big spider web was covering it that was coming from the hydnophora. That acro was toast.

Good to know. I moved mine a bit farther away from the gorgonians.

Only if mine touched something did you ever see sweepers(1 1/2"+). And man could they ever cause damage.

my 8 inch square fluorescent hydno never hurt anything as nearest thing is 1 inch away from it. i find that if other corals ie: monti, poci, most acros. birdsnest etc that dont send out sweepers can live almost within touching distance of hydnos.
