Let me clear this up for you in short: NO PUFFER CAN BE TRUSTED PERIOD!!!
The only so to speak "community" (and i use the term loosely) puffer would be something like SAPS (Colomesus asellus), they are purely freshwater and do better in groups of 3-5+ and seen as you have a 180 housing them won't be too much of a problem, although dentistry maybe tricky...
Otherwise, if you don't mind housing a singleton you could get one of the larger/active puffer such as a Fahaka (Tetraodon lineatus), although they are known to be very vicious killers and will more than likely kill ANYTHING that goes in its tank (with exceptions though rarely)
The only larger puffer is the MBU though that requires a tank of at least 800G+ in the the long run, and the other large species tend to be more lurker/piscivore types (although still not as large as full grown fahaka/MBU)
