My tilapia buttikofferi is alone in his own tank. I noticed today he has a big deep gash in his head right above his eye, my guess is something startled him and he smashed his head into the filter intake. Im a bit worried about him, so how do I go about healing this?
I just did a water change an added stress coat and some salt anything else I should be doing?
