Though I recently regained interest, over the past year I somewhat lost interest in the hobby and didn't keep up with maintenance like I should have, and during that time my Vieja Guttulatus got sick and started developing pits all over his body. Seeing him in that state is what made me realize that I needed to be taking better care of my fish, so since then, I've been doing 50-60% water changes 1-2 times a week, but after about 3 weeks, I'm still not seeing any improvements. I've also been running salt in the tank for about a week with no improvements. The Vieja has been behaving normally the entire time he's been like this. He hasn't been acting sick at all.
Does anyone have any idea what this is or how to treat it?
