A single dwarf puffer needs 5 gallons because they are messy. They need live foods or frozen and have a good bioload for such a tiny fish. If you have your tank well planted, upgrade the filter to one for a bigger tank, and do LOTS of pwc, I have heard of it working in a tank that small, but it's not ideal. Just don't get more than one! They are agressive little buggers.
Also, you would need a very soft sand as ANYTHING that is slightly sharp will injure them. That means no gravel or course sand. And no orniments that are rough.

Thanks for all the helpful info! So no wcmm. I would only get one dp. They have dps at my lfs for only 4 dollars! I can probably get some pest snails for free to feed it. I have a filter that works up to 5 gallons. I also siphon the debris out of the sand regularly, and I do weekly 15% water changes or more. This should take care of its high waste levels yes? I also have a ghost shrimp which will either clean up the results of messy eating, or make a nice snack. For sand, I use play sand. is that ok? Are puffers considered scaleless fish? Will they eat molly fry? thanks!
