I have a Malabar Puffer and I had a True Red Eyed Puffer (passed away from old age)
Both were in community tanks and never bothered any one. My Malabar is with a deformed guppy, betta, black neon tetras and ghost shrimp. She is in a 30 gallon, I would not attempt to put her in my larger tank because of my fear of the filter being to big and possibly sucking her in because she is so small.
My freshwater Puffers all have been docile, but then again they are very small.
