There are messy and clean eating cichlids. Oscar, JD and Green Terror are messy eater as they chew food in their throat and sift through the gills. Vieja and African peacocks are clean eater as they swallow food whole without chewing provided that the pellets are smaller than their mouth.
Every vieja I've had has been just as bad in occasion. Black belts I've owned especially so
