I keep 420 gal in the past and now a 320 gal.I wonder if your tank size is what allows trios/groups to work as every other tank (6’ or 4’ is most common over here for large tanks… our houses aren’t huge) I’ve seen with groups of Cirrhilabrus, Halichoeres and Paracheilinus always fail long term.
I keep harem of Leopards long term 5+ years. Diamond Tail and Eightline 3 years+. I think the Leopards would continue indefinitely other than the fact that they meet their demise in a hurricane. The two flasher wrasses, consider how short their life span is, and the fact that the female did not change sex, I consider this a success.
I also keep pair of Anampses neoguinaicus that spawn all the time, and a pair of Halichoeres iridis. I do believe that the male suppresses the female from having sex change in these species. While there are some chasings and showing of dominant, the females of these species were not injured.
