Anybody ever have a cichlid that one day snapped. for example my JD who was impaired with a battle with our jag (RIP). Jag took supremacy in my families 125. A few weeks later the jack who is under 5 inches in one night killed everyone, like chainsaw massacre style. i fear putting him any where near another fish so i kicked him to a 55. my parents were pissed when i explain that all the other fish were dead. and every day he acts stranger and stranger. anyone explain or have similar story
