Hi, My goldfish's anus has some thing sticking out of it and it seems to have problems going to the bathroom. Ive done the medicine trio and added aquarium salt but it's still the same. Picture attached.
Ph 7.8, nitrates 20ppm, nitrites 0ppm, ammonia 0.30 ppm (changed my ammonia filter, did 30% water change, and stopped feeding for a few days), Gh 143.2 ppm, Kh 53.7ppm, temp. 74 degrees F
