Hey y'all! I was checking on my fish and noticed that my Oscar had a big gash on its head. I know it happened today, as there was no gash this morning. How should I treat it? Should I do multiple water changes and hope for the best, or can I put meds in the tank?
I attached pictures of him; it was a challenge as he kept moving and only paused briefly.
He is eating well and is active. But he does frequently turn shades and kind of floats on the back edges of the tank, he does this daily, especially in the mornings (I think it is because he is waking up and getting used to the abrupt shift of light and darkness as some of my other fish change pattern/shade in the mornings).
Thank you in advance for any help!
