Puffer fish = no no.
I have a friend that did have one in an 'agressive fish' tank and it did well in there, but besides that one miracle, I have only ever heard of them doing well in a tank by themselves with only other puffers.
If you had a large biotope tank going on with loads of plants maybe (according to dwarfpuffers.com) but its generally not a great idea I have one an their lil troopers I had his tank next to my sorority and he would try to attack them through the glass they are best kept alone they will even fight an kill their own kind
Dwarf puffers are great little guys. If I ever get an extra tank, I'm definitely going to start raising some. While they're okay in groups of their own kind, they're aggressive fish that don't do well with other tankmates.
