My electric blue acara, killua, is incredibly ill, hes been acting weird for about 2 months. He's built weird compared to other acaras and hes more pale. Recently he took a turn for the worse so I put him in a 10gal to monitor him, his eyes are cloudy, red gills, EXTREMELY pale, wont eat, and barely moves. It seems obvious I should euthanize him from an outside standpoint but because I have no clove oil and the next best option is too gruesome for me to handle, I am trying to help him out. Yesterday I put salt and fungal medication in the 10gal and monitored him. He made it through the night and his breathing has become a lot more steady and consistent. I know hes suffering but I also see improvement, what should I do??
