I have a juvenile bristle tooth tang in my display tank for 1 week. I don't have a QT tank, just don't have room to set it up. This one patch showed up today on its left side. I did some new rockscaping yesterday and I'm hoping it is just a contusion against the new rocks. I don't have a quarantine tank so I'm nervous it will be contagious to the other fish.
Please help with diagnoses and recommendations on next steps.
Thank you and happy holidays.
