Untuk mengobati ikan mas yang terkena Aeromonas hydrophylla,
dilakukan pengujian pengobatan dengan kloramfenikol, hijau malakit,
khlortetrasiklin dan formaldehid dengan konsentrasi 0,5 ppm, 1 ppm
dan 1,5 ppm. Percobaan diulang 4 kali. Aeromonas hydrophylla
diberikan sebanyak 1 x 10 6 koloni/ml. Setiap bak percobaan diisi
50 ekor ikan. Hasil yang diamati adalah banyaknya ikan yang hidup
setelah pengobatan.
