I have noticed for the last couple of weeks a strange dark spot on my sharks back. Not knowing if it was his spot or other I have done frequent water changes (levels are good) and started soaking his food in garlic to boost his immune system just in case. I noticed today the spot looks worse. He is stressed, I can tell by the splotches on his belly. He is still very active and eating but I have no idea what to treat him with. Can I use Melafix or something that is antibacterial? I am lost as to the coarse of treatment with him. I suspect this is from him climbing around the L. Rock and in and out of the channels I have made him.
I will be sick if I loose him. Please if anyone can help let me know.
