Zebra daino's are probly the few fishes that would work with dwarf puffers in my opinion. As I stated, I had this combo for a little while now and under my observation they can't catch them. Dwarf puffers aren't built on speed, and at night they are sleeping in their nest. During bloodworm feedings, I see aggression from both my dwarf puffers on each other. I mean this is completely my opinion, but I was giving the op an option to try if he is bent on getting fish with dwarf puffers. I've tried dwarf puffers with neons, platy's, and guppies and none of them worked, and had to be put in my big tank.
