My red Moto's were mean...not territorial like most cichlids. Like a psycho true texas on steroids. In a LARGE community tank I had multiple: butticofri, trimac, dovii (sub adult) carpinte, fenistatus, and owners of tank pair black nasty. Red motos were much smaller and destroyed them. I had to pull the pair of haits fear if they didn't get eaten, they'd get bloat...and my yellow motos were worse. Eating each other and totally wicked. Parachromis is mean. I have never seen an adult managuensis back down and they have giant mouth. The dovii is a tank with teeth and loiselle can hold it's own if in a situation that produces confidence, but but but in my experience mota is always half cocked ready to go
