I got some shrimp for my fishies today, how big should i be cutting the pieces? Can i throw decent sized junks in and just have them tear it apart or should i make them small enough for the fish to be able to swallow them. They are 2 1/2 in RBP. I also ordered a beefheart today since my grocery store didn't have one in. Should be in, in 2 to 3 days. Same question for that, how big should i be cutting the pieces?
