I recently picked up a group of these gorgeous cichlids. I'm wondering if anyone has experience wit tankmates that work well. I have 7 of them that are 6-7" in a 72"x30" 230 gallon. Extremely well filtered. So bioload is not an issue.
 

I have kept them with everything from Geophagus althfrons, Paretroplus nourisatti (above) to Tomocichla tuba, and find anything that doesn't resemble them, they pretty much ignore. Although mine hit over 15" within 2 years, and basically maxed out the tank.
Have also kept their cousin Paretroplus maculatus with Central Americans, and Paratilapia species. Click pic to run video.
 
I had a big male Geophagus Altifrons in the tank but he had to be removed. He was about 9" and he had all 7 Dambas pinned in the corner. Maybe I should start with GEOS that are smaller than them?
 
My Geos were a bit smaller than the menerambo, and is probably why they didn't try to dominate. And there was 3 or 4 of the Geos in the tank with 6 menerambo, so they had there own group dynamic, which kept them busy with each other.
One thing about menerambo (at least mine).
They did not like any sort of change in stock, once the hierarchy was set.
Any change, any addition of cichlid stock, or subtraction seemed to cause immediate chaos.
I pulled one menerambo, at a certain point, and within hours, all menerambo started to kill each other.
Another time, a pair started spawning, and I thought if I pulled the others, the eggs would have a better chance.
As soon as the others were taken out, the pair bond failed, they ate the eggs, and started to kill each other, until the others I had pulled, were returned.
These are a group oriented fish, with a complicated inner group dynamic.
You can probably add or remove non-cichlids dithers at will, but any cichlid changes I tried, usually ended up disastrous once they had matured and their hierarchy was established.
 
I did find a supplier that has more similar size to mine. I'm wondering if I should just pick a few more up from him and just stick with a large shoal.
