I am stocking my 100 gallon (72x18x19) tank and trying to find some interesting african species. Right now, it's primarily polypterus and ropefish, and an african knife. I was planning on adding some ctenopoma acutirostre to the tank eventually. My question is how well would a h. odoe do with the knifefish and ctenopoma? I've read they do well with bichirs, but also realize that they are a predator and the others may appear as prey to them. Anyone tried this combo?
