I have a 55g high tech planted tank. I recently rescued a nearly blind African knife fish (Xenomystus nigri) and now I'd like to add some more congo river inhabitants to the tank. It was suggested that I add an African leaf fish (Ctenopoma acutirostre) and a senegal bichir (Polypterus senegalus). Ive never had any fish like these before; Ive raised Oscars, EBJDs, and green terrors in the past. I would like to know if a bichir would be safe in my planted or if they uproot plants like big cichlids do. Also I was told by a petsmart employee who was actually rather knowledgeable that he owns a 10" senegal and that its the meanest fish he's ever owned. Is this fish going to be a handful? The tank is in the livingroom and I'd like it to be a little on the calm side.
Here is what my planted tank look likes.
