I am in the process of setting up a 75G, and will be moving a Yellow Watchman Goby and 2 Ocellaris Clowns from a 29G. I really love "Grumpy Gus" the Yellow Watchman and would like another "personality plus" goby or Blenny ( or 2), in the 75. I really like the looks of Diamond, Orange Spotted, and Pink and Blue Gobies, Lawnmower, Midas, and Bi color Blennies, but am most concerned with compatibility for Gus and allowing him to keep his great personality. What recommendations do you have?
