I agree with the common pleco comment. african mbunas get too aggressive for bristlenose, however stranger combos have worked. apistogramma are pretty cool little cichlids. i think you would need to lock down the region to african or non african. I loved keeping victorinas. the colors were incredible. I don't think they are as uncommon as they used to be. thanks to a few people in texas, , i think they have filled a few more tanks. I know that I can get vics shipped real cheap. anyhow good luck. you may just need to get some more tanks to house all differnet kinds of dwarf cichlids.
