My Goldfish has a swollen butt, and I am not sure what is going on. In the last two months I have went from having high ammonia, to Ich, to high ammonia, to this now. One of my Platys was pregnant and she started to have her babies only they were all deformed and still birth. Her butt was swollen too, my ammonia levels are down to safe and I have not seen any more Ich on my fish but my Goldfish has been chillin at the bottom not eating much with clamped fins and red lines through his fins. I have lost a pleco, three platys, a neon, and a bala shark all in the last few months. Please help me!!!!!!!!! Also my Goldfish's eyes now have black spots in them. I read they could be burns from the high ammonia, a few of my other fish had some spots on their gills and mouth.
