i used to feed them to my cics, pretty good price, but they are really messy...even if you break them apart prior to feeding. my jags and fh would fill their mouth to max capacity and end upgrinding them an spitting them out over and over again
Find a bait shop if you are set on feeders. Much cheaper....
Sticks aren't really a good idea for a staple diet, its better to have no one food as the staple diet. Constantly mix it up, don't let them get addicted to just one food type.
Last night i bought 6 guppies because my pike is only 2 inches,he totally ignored the guppies and tried to eat a Black skirt Tetra instead,it seems he only wants feeders that are actually too big for him to eat.This pike is a real killing machine,he knocked off 6 Tetras in about 45 minutes.
