Hello, I’m new to reefing. My current setup is a 32.5gal with a pair of clowns, 1 banggai cardinal. I would like to eventually add 2 more fish. I would like to add a Green Clown Goby and a Royal Gramma. I’ve heard the Royal Gramma could be hit or miss with aggression so my question is should I add the RG last? Or would it be best to add him next and then have the Green Clown Goby figure out his own hiding place when he’s added last? Or does order not particularly matter with these 2 fish. I’m just worried about territory if they are both cave dwellers and enjoy hiding.
