This is a Dwarf Angelfish
Here are some physical traits that might help ID this species:
- Orange primary pigmentation
- Dark, vertically-stripped patterns on top flank - strongest at the head and increasingly faint but visible all the way to the tail.
- Oculi on the rear dorsal fin
- Blue coloration around eye, dorsal fin, and anal fin.
(note: missing portion of the top dorsal fin is due to shipping damage).
