Puffer diet

[burrows14]

hey folks!
just bought myself a small 3" porc puffer this weekend and HES SOOOO COOL!!!

I did some research on them before i got him and have been searching CR for more info on a ideal diet for him. ive noticed that lots of people claim to have the best diet for their puffers and im hoping that thet would be willing to share. Right now he is getting frozen krill soaked in selcon+garlicX. I wanna feed him some shellfish but when i go to the store i see frozen stuff with a bunch of other junk added to it. if anyone could help me it would be much appreciated!

cheers
Ray
