I've been reading and investigating the forums and misc. sites lately on a good fish for a small aquarium (15 gal). After watching many videos I'm loving the dwarf puffer fish right now. I was hoping to find someone with experience with these awesome fish. I'm hoping to get 2 females and 1 male dwarf puffer and have them in there with 2 Oto fish. I'm reading that the Oto is pretty much the only fish that gets along with the dwarf puffer.

Any suggestions would be appreciated.
