I currently have a 20g waterbox with a clown pair and a banggai cardinal fish. I want to look into adding a yellow watchman goby and a pistol shrimp pair to this tank. I’ve heard this should be fine on bioload but wanted opinions. My main concern with this many inhabitants is when I eventually start adding bubble tip anemones for the clowns. My main goal is to have this be a heavy BTA tank with the clowns but as this is a newer tank it will be a few months until I add BTAs. Once I add them should I be worried about added aggression to the cardinal or the goby from the clowns? Willing to rehome the cardinal in the future if that might be an issue.
