A couple weeks ago i switched my piranha to frozen bit fish instead of live feeders. I've been using mostly herring and sardines. sometimes they eat, sometimes they dont. i really dont think they like eating stuff sitting on the bottom. And its a real pain to fish out the uneaten pieces in my 140gal planted tank. Plust it makes the piranha rather upset any time i have to put my net in the tank, especially if it goes down to the bottom where they hang out. I was wondering if anyone has tried running fishing line or something through their food to suspend it in the middle of the tank.
