Hi I have a 15" Jardini. He had tail rot about 10 months ago but did get better. Recently it is looking like it is coming back. Water quality is perfect, 0 Ammonia 0 Nitrite, 0 Nitrate. Ph 7.6. Diet is Superworms, some nightcrawlers. Any advice I would appreciate. He is in a 60"x24"x24" tank temperature is 82, 40% water change twice a week. Thank you.
