Just under 3", this female msobo is the most aggressive fish I own. A few months ago she killed two other female msobo's and severely wounded the third. Recently, while mouthbrooding, she herself was nearly killed by the fully recuperated female(retaliation?) losing all her eggs and tail fin in the process. I placed her in a hospital tank containing a single yellow lab and an armored hoplo catfish. Within a few days the bruised female killed the lab and harassed the catfish. I placed her back in the original tank (due to lack of tank space) and the two females instantly engaged in a liplocking battle, fighing to a draw. By the second day she nearly killed the female which had beaten her earlier (forcing me to place the loser, lacking even less of a tail fin, in a fry tank; luckily she's left the juvies alone and is quickly recuperating). She's there to stay while this female remains in the demasoni tank since apparently these female msobo can't tolerate each other (meanwhile the males are fairly laid back).
