Danny - as I first recommended, you should have that BTA near the surface. I'm concerned that with your lghting and tank depth the penetration will be lacking. Is there a good spot closer to the top of the tank? If not, I strongly suggest arranging your rockwork to accomodate the BTA.
Then, feeding will be a breeze.
It took small pieces of mysis quite easily... A pair of aqua-tongs is quite useful as well.
As for the female clown, she needs a bit of a spanking now and again... show her who's boss.
