ok i just set up my cichlid tank because i had my cichlids spread through 2 tanks and i combined them, its a 55 gallon with one mbuna ( not sure what kind) a red empress, a fusco, a bulldog pleco and one upside down cat. my question is the red empress was in a tank with the fusco and they were fine but they are now fighting and the red empress is hanging around the filter pipes. what should i do stop this it has been going on for about four days now and the empress is looking a little tattered. thanks
