Where I was living in Portland OR the water was extremely soft and trended in the 6-7 ph naturally out of the tap (and later I learned that due to the softness, the pH would drop even further, below 6.) I think that helped with some of the SA species. I did use leaf litter until I learned how low my pH was dropping, then took it out.
My checkerboards weren't as robust or long lived as the others, though. Only a couple years. Maybe with all the leaf litter there'd be even longer term success.
Here are pics of the male. I had the maculatus. Also WC. I think the filamentous can be found CB maybe? Might be more long lived if so?
My checkerboards weren't quite as in your face as some of the other cichlids, either. They were just more mild in general. I do like the in your face fish that interact.
