Thanks for reaching out about your fish. Dermatitis can be caused by poor water quality, bacterial infections and parasitic infestations. Checking water quality first, is the easiest. Correct any concerns. A skin scrape and microscopic examination is needed to diagnose parasites, as different parasites require different treatments. Antibiotics would be needed to treat a bacterial infection. Seek an examination with an aquatic veterinarian. Good luck.
