Very nice idea, Mr Desireless.
Two small things need to be taken care of. First, the litlle holes in the bottom make the bloodworm or the sinking pellet goes through it. (There is special sinking pellet produced by the same producer of Japan Ranchu Lord called Tosa Queen, my friend bought it in Singapore some years ago) Is it possible to put something in the bottom of the basket? Second, the basket will constantly moving and when it reaches the water fall, if the current is too strong, the basket could flip over and the piranhas will be very happy. So I tied the basket to something that it will not move close to the water fall.

I imagine the tosakins will constantly sweat all the time thinking of their fate watching those piranhas watching and talking about them every day
