Wantanabei skin issue?
Actually.... The second pic using a phone and moving fish is quite good. First pic is fuzzy, however, marks exist on both sides of head and can see in fuzzy pic. In second pic, It's the whitish mark about the size of the pupil just back from the top outer circle of the eye. I use QT for fish and corals always. The feedback I'm looking for is specific to this species of angelfish. Perhaps, ulcers around upper head happens in this species kind of thing....
Marks were not there before going into display. Could be a tight squeeze through live rock. Will watch to see if changes shape and/or gets worse before I remove. It's not ich. It's not velvet. Fish is active and eats like a horse at the moment.
