Penguin,you MUST stop eating the bait pillies.I know how much you want those tiny little legs of yours to grow,but you are messing up that nice "Black Tie" suit of yours !
On a more helpful note those Kings CAN be turned from lookers into takers
They are following the Trevs in hopes of 'stealing 'their food ,much like a bunch of seagulls will fight madly over a piece of bread while a chip lies unnoticed in the gutter. It is the COMMOTION that attracts them.
When you raise a fish that the kings follow dump in the water 6-12 finely chopped pillies IMMEDIATLY you see them,before they go back down. Then feed cubes 1 or 2 at a time with a hook embedded inside 1.
And bingo you're ON !
