Problem is finding sizeable cons to keep up with the size of the 7 inch male parachromis. Right now I have 2 thorichthys aureus with them to try and thinking about getting more or getting 3-4 inch firemouths. I know they aren't as tough as the cons but maybe a group of firemouths can work, not sure. The male parachromis has t snapped yet, but all it takes is a blink of of an eye and it's still a parachromis lol
