Parachromis managuense has a bad reputation, just like many of the other large predatory cichlids. This reputation is largely undeserved, and besides, the positive sides of these fishes more than make up for any negative ones. Not to mention that an adult P. managuense is incredibly beautiful.I've kept these cichlids and have nothing but good to say about them as long as you have an aquarium large enough to handle this species that grows to 55 cm/22 inches. I would say that the absolute minimum .
