Best Food for a Dogface Puffer?

[Palster]

I picked up some Krill today. I put the Krill on the end of a shish kabob stick and the puffer immediately gobbled down the krill when it was placed in front of him. I ended up feeding him several Krill which he readily accepted. The Puffer now goes after the shish kabob stick and chomps on the end as soon as I put it in the tank. Once this fish starts to become more active and gets over the stress of being moved I will start to feed him something a little bit harder to ensure his teeth get worn down.
