I’m new but kept a 10 gal for a year and a half and just started a 20 long and a 40 gallon AIO. In the 20 long, I have a Pajama Cardinal and wanted to add a couple of other fish. I went to my LFS and picked up a yellow watchman goby (always wanted one) and also a fish I hadn’t seen there which I later found out is a Court Jester or Old Glory, and also a goby. So far the watchman enjoys his holes and caves and hangs out near the sand while the Court Jester swims the perimeter. Is it possible for them to coexist or will they be incompatible since they are both Goby?
