7-8 years ago in my pre-reef days I kept a six pack of YT damsels . I wasn't as observant as I am now but I do remember the 6 damsels each set up their own little territory and defended it against other YT damsels. It was very cool but it was like a bunch of pitbulls on imaginary short leashes. From what I remember they left the other fish alone as they were pre-occupied with the other YT damsels.
Will a six pack of YT damsels leave other fish alone and defend their territory against other YT damsels?
