Your sure not even one more cichlid? I only have more common species right now(which I like) and wanted one or two less common species like a salvinis and or the loisellas cichlid which is supposedly really calm and small compared to most parachromis. Yes I know most parachromis need a tank to themselves or a larger tank to be with other fish(like jags rtms ect), but from what I've heard these guys are like as aggressive as a jd and similar in size(slightly larger) and for the bottom dwellers I want to get another medium sized cat or two and maybe some dithers and water quality won't be an issue. Also what are some recommendations for some non catfish that would go well with my cihlids, I was thinking possibly a school of silver dollars but idk, birchirs are cool, I had one once but the one I had a while back grew very slowly and I don't want the Oscar to grow fast and the birchirs to stay tiny and end up with an expensive and possibly deadly meal for my Oscar.
