Hi everybody,
my Zebrasoma tang for no obvious reason stopped eating and hiding all the time behind the rocks (def not normal). Problem been noticed about 4 days ago. Tried several different foods (green nori sheet, 2 types ocean nutrition flakes, frozen Mysis - no luck), it just ignore it, looses its rich yellow coloration and its skin looks sort of "rough".
40gal 3 year old tank and this fish is w/me for almost 2 Y. No fish or corals were added to the system in the last 8MO.
Made several photos if that may help ID the issue. Please help, advice on remedy.
J.
