I currently have a 180g setup, mainly african cichlids (Frontosa mostly) and i have an 8" Ornate bichir in there as well. I simply love polypterus and i was thinking of adding 2 or 3 more. Does anyone see a problem with this? Perhaps in the long run they would outgrow the tank and i would need to setup a 2nd system, but other than that does anyone have any comments?
