#aficancichlid

I have a 150 gallon tank with mainly mbuna and haps, was wondering if there are any outside of the box fish ideas that I could put in there? I also have 2 convicts and 3 synodontis and a striped Raphael catfish

Hey fellow fish keepers I pick this guy up as “ African cichlid” but through my research I believe him to be an orange blossom peacock cichlid , but if I am wrong please help me out also can we get a positive sexing on this guy? Also does anyone know a little natural history on these guys?
