Well judging by my name you know that I like puffers. I've had all different types of freshwater and saltwater puffers over the last 23 years. I feed my puffer every other day or so with your typical carnivorous foods (shrimp, mussels, squid..etc). One day when I was feeding the other fish I saw the puffer eat pellet food. I couldn't believe it! In all these years I've never seen any of my puffers go for flake, pellet or any other food besides frozen seafood. Has anyone ever experienced this before?
