Dude, puffers are pretty generally psychotic... the smaller lurkers like hairy puffers are the worst. Dragons get a lot larger and are also lurkers but even I (and I have a 16 inch fahaka in a community toy tank) would shy away from mixing puffer species. They CAN get on with other fish but are psychotically aggressive against other puffers in my experience... you can try but be prepared for heartache.
