try having three 14" pbass that will eat over 100 goldfish and rosies mixed in about 10 minutes. i sometimes just dump in all of them and watch the feeding frenzy begin. there is water flying out of the tank fish running everywhere trying to dodge and stay alive just a frenzy of pbass with mouths full of feeders to when the open up u see the little eyes and mouths of the feeders just looking and hoping to get out. ITS A GREAT SHOW SCARRED THE HELL OUT OF MY BROTHER-IN-LAWS AND ONE IS A MARINE HA HAHAHA LOL
