Has anyone ever heard of an aggressive Mbu? I thought they were peaceful, but my Mbu has recently decided to kill my fire eel it shared a section of the 90 gallon with, and had been trying to get at the jaguar pair (who were trying to get at him too) on the other side of a divider, even trying to bite them through the divider, and even the divider itself a few times (the pair has their own tank for now.)
