So I've had this GSM pair for about a year housed in a 50 g cube by themselves,female 3" ,male 2".I just moved them to a 5' 120g with a large rbta where they were alone for 2 weeks.I added 2 wrasses and all hell broke loose,female is constantly charging the other 2 fish to the point that they constantly hide.I had intended to stock this tank with a good number of fish but it seems the GSM won't allow this to happen,these guys get big and aggressive and they're not getting a 5' tank to themselves,would my plan work with a mellower pair,occelaris,snowflake or something else?
