The frayed fins could be a tank mate picking on him. At night. The reason a say this is because I used to have a male auratus who was a serial killer. At night during the day all my cichlids would go about doing normal cichlid habits grazing on algae and what not. And I couldnt figure out who was doing the attacks so i stayed up one night to see if i could catch the culprit sure enough its was my male auratus
African Cichlids are my drug
