I apologize for the grainy photos! This is one of 12 damsels currently in my QT tank and I’m not sure if this is uronema or just an injury/injury and bacterial infection and I don’t know the course of treatment to take. My QT tank is 40 gallons and currently housing 7 yellowtail damsels, 5 azure damsels, a coral rabbitfish (3 inch), and dussemeri tang (4 inch)
