feeder centipedes?? i just go to the garden and dig up some soil and i can surely find some...sometimes i would go on a trek to look for bigger ones or they may just pop up in the drains...so i just catch them and toss them into a pool of death...i get rid of the fangs first of course..with tweezers and wire cutters. apparently some pple believe that the more poisonous stuff you feed your arrowana the more vibrant the colour gets...heh...chinese superstition/belief or truth that's up to you..
