Very interesting. How many blood red and King Kong Parrots do you have in your 125G and what are their sizes? A PIC of your tank and fish would be great.
I once had 3 large blood red parrots in my heavily stocked 125G Hap, Peacock and mbuna tank for years but despite quickly growing to a large size, eating well and seeming to thrive, they all eventually died at different times over an extended period of about 3 years. No signs of damage to any of the blood red parrots and no other fish in the tank perished other than a few due to obvious violence from the other cichlids, usually I would just find a few bones during a tank cleaning. Random violence just seems to be an inherent, inescapable part of keeping a mixed tank of African cichlids. If I kept blood red Parrots again, I would dedicate a tank to only them (and a few catfish) like you have successfully done.
