dont flame me but i find it easier to do a community with a overstocked tank because aggresion really spreads out and so far my 180 g is full of 3-6 inch fish and no deaths here is the stock list, also all fins are perfect, but what you have to do is remove all the aggresive fish and everytime i have a super aggresive fish i sell him and replace him but so far i only replaced 1 mean texas but he was 7 inches big , dont hate me but my fish are all healthy and thriving , i just have lots of hiding places
