Hello, I have 2 goldfish and they turning bright red where their fins attached to their body. I did a treatment of API Fin & body cure and the redness is mostly gone.
Now one of them will slowly swim to the surface, take a gulp of air and then swim erratically. Doing twists, rolls. He’s eating and swimming around the tank. Some thing else is I think he has very poor eyesight. When I feed them green peas he has trouble seeing the peas on the bottom of the fish tank.
They are in a 75 gallon tank, There’s one fluval fx6, two aquaclear 110 hob filters, two air stones. I am also using 2 bags of Nitrazorb in the hob filters.
Water parameters are…
ph 7.1 ammonia 0.0 nitrite 0.0 nitrate 7.0
