Last week, one of our black skirt tetras developed gill disease. I thought it was gill flukes, but, a fish "expert" said the symptoms (inflamed gills, red underneath) said it was gill disease. Well, we hospitalized her, treating her with "Nalasol" (Nalidixic Acid), and a week later, she's improved but still doesn't eat, and hangs out at the bottom. Should we try a different med?
