Torch sweeper tentacles...24/7?

[Reefpuck]

Got this torch about a week ago...and I honestly don't think they sweepers have taken a break. It's relatively close to another torch, however with the way the flow works down there...the sweepers only sway one way and never hit the other one. Is this normal for a torch? The torch on the left has never shown sweepers...

I've seen them do that in areas that have strong laminar flow, which I'm guessing is the case there?

I'm more interested in the other one never showing sweepers because neither has mine.

So you think if it was in a more random flow area it might help?

Mine do a lot better in random flow. I have noticed they tend to lengthen or shrink the thickness of the tentacles in high flow.

Yeah I don't think they like getting blasted on just one side, it's unnatural and might be what makes them extend the sweepers in a defensive move.
