Rid my tank of...2 yellow Damsels and a Pseudochromis

OK I have 2 yellow Damsels and a Pseudochromis
(the yellow one with the purple stripe going down the middle, nasty fish)
I HATE these fish. I bought a fish trap, the canning jar one on
ebay...caught me some snails

I want to literally kill these fish, I've tried the feeding thing with the
net.
What else is there ?!?! Can they be blinded by a laser pointer ?
Do they make little harpoon guns? How about if I lace some food
with poison. I actually am about a week away from taking everything out
and then putting it all back in minus 3 fish.

Oh god that poor 6 line wrasse I just dropped in there today !

Any suggestions ?
