I thought I read somewhere that you can use decaf green tee to treat fin rot, does anyone have experience with it? I bought a fish yesterday and he is a mess; his fins are shredded and rotting, and he seemed to have difficulty breathing, though his breathing looks a little more normal today. Right now he's in a 1 gallon hospital tank treated with Prime and aquarium salt and heated to 77-78 degrees. Does this sound like a good treatment for fin rot? Would green tea be safe/helpful?
Also, does anyone know what those black spots on his dorsal fin are? His normal color? Fungus? Fin rot? Something else?
He also has some dark spots on his body (you can see those best in the second pic), are they lacerations/scars?
