Our blue hippo tang has a bunch of dark random sized marks on both sides of her body.
No fish have been added in 3 months, and all were QT before that. Recently (2 weeks ago) added a BTA and two tuxedo urchins both from fishless systems.
Installed a carbon/gfo reactor 5 days ago.
Could this be anemone or urchin stings? Or a reaction to carbon?
No other fish are affected but a clown had some tang swipes a week ago. These look different than that did. Also appears too big for black ich.
Any ideas??
