When going to clean my 125 today I noticed this scratch at the bottom right portion of the tank. I have no idea what could have caused this besides maybe my fahaka. He will randomly charge the glass and show his teeth but haven’t seen anything like this.
it isn’t incredibly deep but it is something I can feel from the inside of the tank. Should I be concerned or do you think it will be okay.
