I noticed the front of my 75 gallon on the right side has these fine scratches going from the bottom of the tank all the way to the top. I’ve had the tank for about 1 year and a couple months. Not sure how long they’ve been there. You can only see them if you are on the ground looking up to the tank. Will those cause any problems?
