So, I know that every specimen comes with its own personality, but I would like to get some guidance from the assemblage. I have a Valentini Puffer in a 50g cube. He has been by his lonesome for four months now, and I would like to add at least one more fish to the tank. My wife would like to add either a bi-color or starry blenny. All the information that I have seen online seems to indicate that the Valentini should be compatible with most other peaceful fish, but I would like to get some first-hand accounts if possible. Appreciations in advance.
