Hi everyone I believe my fish are suffering with flukes. Although I’m not 100% sure I notice my parrotfish not eating and flashing. He also looks a little pale. I tested everything and ammonia was zero nitrite was zero and nitrate was 25. I also have a gourami and his gills looked a little red which led me to believe they had flukes so I bough Fritz’s prazicleanse and added it to the tank. If you need pictures of everything I will gladly provide but I will probably do it tomorrow the 31st because it is getting late for me.and pls no hate because I am not that much of an expert so please help me in any way without judging…
