Oscar wounds

Question
Hi, I noticed that recently our pet Oscar (about 6 in long) keeps getting fresh scratches and wounds, I think he also damaged his jaw. We only have 4 fish in the tank (about 70 gallons) and he is the biggest one. He still eats but not as well as before. Thank you, any help is greatly appreciated.  

Answer
Hi Olga,
 Biggest doesn't always mean that another fish is fighting with him.  I would keep an eye on the other fish.  Do you have lots of structure in the tank, e.g., wood, rock, plants, etc?  More structure will help reduce aggression.
