Most people agree that they can be kept in Hermes.I know 2 people with groups of 4-6.

I also like to keep Royal Gramma in group. I have 6 in my 320 right now. Very colorful and peaceful. They retain their brilliant color and will spawn in your tank if you keep them in good condition, otherwise, they have color fade.
They are dimorphic with the male, the largest, will have longer pelvic fins and the purple extended farther down the body. I would say female and juveniles have purple extended just pass midway, while the male have purple almost to 2/3 of body length. Female and juveniles pelvic fins just barely reach anal fin while male pelvic fins reach 2-3 mm past the origin of the anal fin.
Male Royal Gramma will fight each other to the death like fresh water Betta. In one of my old tank (450 gal) the male of my harem got old and weak, one of the female turn into male and promptly killed him. The younger male attack. They lock jawed and the older male lip was ripped. He keep on attack until the older was running and tattered, destroyed one of his eyes and I never seen him again. I guess he died and consumed by the CUC. There was not much I can do to remove him in a 450 g full of corals and rock. That is about the only aggression I ever seen regarding Royal Gramma. They like to show their jaws a lot to fish that go into their territory. However, this is just all bark and no bite. I have never see them dash at or take a bite at another fish.
IME female can change in to male very quickly in the absent of supression by the male, even small RG can cnage to male in as little time as a week or two. They will not look like a male until the phycical change take place but they will act like a male.
Best bet, if you already have one in yourtank, is to have LFS order seveal and put them together they buy all but the largest one.
If you don't have one, then have the LFS put them together in a tank and take all of them.
Many LFS put them separtely, after a few day these are all males and should not put back together.
These guys are difficult to take picture of. I snap one with my phone that show the dimorphism of RA. The larger one , look smaller here because he is far away is the male and the other is one of the females.

Almost a year. I have never had any issues with them.How long have you had the group? Most groups of Firefish eventually turn into one

Love the school of fire fish. They stay in the current and out in the open. My Royal Gramma is much less shy since I added the fire fish.
