Hello!!! Hope everyone and their fish are doing well!!!! My Oscar has been attacking his reflection . I was wondering if that was normal for them to do.
 
Yep he just thinks it's another Oscar and is defending his territory. My GT does it all the time. People who raise florwehorns sometimes put mirrors outside of their tanks to promote this behavior.
 
I have been doing a lot of research on this for a flowerhorn I have and wanted to add that leaving a mirror or something that casts a reflection all the time can be extremely stressful for the fish. So exposure to reflection should be limited.
