Those have got to be some of the cutest puffer pictures I have ever seen.
Seeing all of your puffers makes me want to get some.. so once my birthday tank is all set up and the guppies have a new home, I am getting a dwarf puffer for my 5g. [Have no fear, my water paramaters are perfect -- my LFS tests 'em weekly with their master kit as me = poor student with no money for a test kit.] I think a DP would make the perfect desktop distraction.
