Thank you Luimeril
. I will add salt during water change today. I don't understand. He used to be a very active fish. Why is he so dull now? What did I do wrong :(
I know these are not the best pictures but can you check the close-up shots of him from past & now and tell me if you see anything alarming? I am worried that if there is something wrong with him, then I will be late to start the treatment. At the same time, I don't want to give him medications if there is nothing wrong and he is just stressed that's all. That's why I am asking. Thank you.
