No, but that actually sounds like a fun way to grab them if you're fast enough. :D
I picked out just the clear suction tube that was about 1/2" wider than his fins when spread so he wouldn't feel too confined. I put some sand on the entrance so there was depth of vision with it all being clear. He checked it out a few times and once he got a piece of floating shrimp debris he went right in looking for more. They'll swim forward before trying to swim backward so you have a second or so to get a net on the open end if an escape happens. In this case he darted to the end, smacked the end hard, turned around a couple times and I got it vertical and covered with the net before he figured out what way was up or out.
