I'm pretty sure the tethering is for us. The (living) fish wouldn't care about maintaining a central position in a tank.

Yet it makes the fish appear to be making progress in the moving water. Sure it's wriggling side to side, very neat. But keeping up with the current? Sure, if it's held there by a wire.

Right, but notice the part of the video where it actually swims forward and creates slack in the wire.
