No doubt it is designs for a Fish Trap made out of drink type bottles.
Cut off the end and invert it back inside the bottle... stick a bit of food
in the back end of the bottle as well as a small rock or sand and lower into
the tank.....
Wait for possibly ages and with any luck... you'll have your fish.... or at
least all your crabs and other things that fance the bait...

I have used this method before, it works but not always.

I saw this on Ebay the guy claims it will remove unwanted fish.

I was interested in seeing what it looked like.
I thought that the picture was so ugly, maybe he thought it would make the
unwanted fish jump out in order to not have to see that after the sign
gets
taped to the glass.
Further reading says that he's selling his idea for the device. If
that's true how come the quantity available is 78?
