초록

A blood parrot (Amphilophus citrinellus × Vieja melanurus) cichlid showing a flared left operculum was sent to the Fish Disease Clinic. The fish showed intermittently irregular ventilation and reddish soft swellings located at the ventral part of the left branchial cavity for one month. Other abnormal symptoms were not observed, and the appetite was normal. Only a putative diagnosis was conducted based on the history taking and external symptoms because the owner did not want an invasive biopsy or other potentially stressful examination of the fish. Therefore, considering the information available and the treatability, goiter (thyroid hyperplasia) was suspected as the top differential diagnosis, and the empirical treatment of administering iodide (0.03~0.015ppm) in environmental water was conducted. The treatment was discontinued for six months because the swelling was noticeably reduced. Body color became pale, but other abnormal signs were not observed.
