    Lately my yellow coris developed a hobby to fight with his mirror image. That is fine. What's annoying is he keep splashing water out of tank. To glass & floor, and my tank is open-top.

    I have been trying to stop the behavior by tapping glass & using my face to scare him, but the guy is careless.
