i have a 55g freshwater tank that I’ve had for 9 months. I’ve been having a lot of issues lately and the latest is intestinal parasites. My male angelfish has been not feeling well or eating for a few weeks. He has a bloated belly, rapid breathing and clumpy white pooh. This morning I added api general cure to my entire tank because I think other fish are infected too. It’s been a few hours and my male is getting worse since starting this treatment. He’s up at the top of the tank, rapidly breathing. Should I discontinue treatment and let the parasites pass on their own? Is there another treatment that might work better and be less stressful on my angels. Water levels are all normal btw.
