The bluegills will eat anything....depending on how you got them...if you hooked them...give them a day or two....you can add salt to the tank to help facilitate healing...But if your fish wont eat....just have to let starve them a little...not to be mean...but it works...thats what they do at fish farms....even Largemouth bass will eat pellets...if you pellet train them...its heartbreaking thought to see them with their empty stomachs....going all skinny...I think one of the most nutritious food is the Grass shrimp...at the pet store I go to they cost $1 for 8 shirmps...about 1 inch....really expensive...I was wondering if anyone knows any local lakes with populations of grass shirmps in it....I'd like to get some...
