A couple days ago I started treating my crown tail for fin rot. I bought a heater for his tank and I am now keeping it at 78-80°. I also bought some aquarium salt and gradually added up to 1 teaspoon of aquarium salt with his water changes. For the past two days of treatment, he as been lively and has had an appetite. However, today when I came home, the water looked a bit cloudy and his fins were very
clamped. I poured his water into a bowl and kept him in it, and cleaned his tank thoroughly and refilled it with water with the same temperature and salinity of the water he was in. I put him back into his tank, but he has showed no improvement since this afternoon. His fins are still very clamped, and he is mostly hanging out at the bottom of his bowl. He doesn't have an appetite.
