Royal Gramma Question

[NewbyReefer]

I have a royal gramma in a 135 for about a year and a half with 2 tangs a sixline wrasse, blue manderine, and 2 dwarf angels. The newest additions are the tangs witch are about the size of 2 thumbnails. My question is, I know people and know of people that have housed multible grammas in a tank but I cant seem to pull it off. Ive tried to add more on 3 different ocations and they just don't make it. I was wondering if they are being harassed by the established one or one of the others. Everytime I add them they dissappear in the rocks and are never seen again. The longest i've had one make it was a week before it disappeared. I was wondering if theres a way to do it or if its just going to be a one gramma tank. thanks for any imput


Added note. When I attempted to add more royal grammas there was only one dwarf angel and no tangs.

It can be done, but its tricky. I would capture the existing Gramma and put it in an isolation chamber within the tank. Then add two smaller Grammas. Give the new guys/gals a couple of days to get cumfy, then release your larger Gramma. Hopefully, at least one of the new fish will be female. Then add some macroalgae and you may have them spawn. I've had them breeding in a 55, so I'm sure it can be done in your tank.
