Green spotted puffer and knight goby?

Question
Hi! I have a green spotted puffer who's about 1 inch long in a 10gal brackish tank. He's really happy and greats me when I come to feed him. I was wondering if i could add a knight goby to his tank. My puffer is mainly near the top of the tank and near the middle. If I can add the little knight goby would there be any plant arrangements such as sort of a plant wall to keep them mostly separate, or is there no solution? Thanks in advance!

Hi Will,
From my own experience there is really nothing that can go with a puffer for long. They are simply too aggressive, and anything aggressive that is a lot larger than them can easily eat them. The only thing I can think of that will survive peacefully with a puffer are hermit crabs.
