i came home yesterday to find that my whole tank was messed up . Rocks were upside down, plants were moved and the gravel was all to one side. Whilst i was cleaning my tank up i noticed that one side of my oscar's scales was partialy missin ang that both sides of it's tail was damaged. It's eyes were also poped out. I then looked at my flower horn and parot fish which also had simliar injuries. Any advise on what happned?
