Stocking 125 gallon. Green Terror and.....

That's awesome that the GT's don't cause your rainbows any problems. I have several Bosemanne is another tank. sound like everyrhing is going smoothly. Are the GT's adults yet?

My terrors never mess with the rainbows. The rainbows were added after my terrors were established in the tank and things still went smoothly.
My male(10”+) is over two years old and my big female(7”+) is nearing three. My little female(5”) is just over a year old. So I’d say they are adults.
My big female causes minor problems with my male. But that is because I had her for nearly a year before adding my male who was a tinny 2”. She has never liked him being the dominant one in the tank.
So if you avoid making that mistake you shouldn’t have any problems.

What size will your GT be to start out? I've had a good number of rivulatus GTs over the years and had no problem keeping them in cichlid communities, from Africans to Sevs, geos, and other SA cichlids. Wouldn't do it myself but I once saw one in a discus tank years ago. I know discus, having kept them myself at one time, it's easy to tell if they're stressed but these discus were quite happy. One of the more memorable display tanks I've seen was an all adult male orange edged GT tank some years ago. The list of possibilities is actually fairly extensive if in the end decide to do a GT. One way to get ideas and see some of the possibilities is to google 'green terror community' and view some tank videos on youtube.

No denying that different individuals can vary, but to some degree starting them out small in a community with other fish seems to socialize them, as opposed to giving them a tank to themselves, then trying to add other cichlids, or keeping them with a single similar sized cichlid. I've also bought adults that already got along with other fish and added them to my tanks. In any case, as I say, they've worked well for me in a variety of setups.

A potential exception are conspecifics. A clear exception are wild rivulatus, which I've had. Mine wouldn't get along with much of anything, including each other.

IME Terrors are pretty good at establishing a pecking order and getting along.

That being said, it only will work if there is NOT a breeding pair in the tank.

I think If you want GT as the centerpiece then you should get a group of 7-10 juveniles and let nature take its course. A pair will most likely emerge and then you can pull the extra individuals back out.

I've had great success with Giant Danios as dithers. They are lightning fast, will eat lots of different foods and are big enough that until a GT gets full grown probably won't do anything to harm them. They also never stop swimming if there is a current in the tank from a powerhead.
