Thanks for reaching out about Dart and including photos. The lesions are not clearly visible in the pictures but by the description, could be parasitic as in salt water ich (cryptocaryon). A veterinary visit could provide diagnostic services, as a skin scrape and recommend a treatment plan. Other fish will be affected so treatment should include the entire aquarium. Good luck.
