Hello....in need of advice please! I'm fairly new to the fish scene and loving it. I currently have 3 half grown Oscars in a 55gal, I just purchased a new 125 setup to upsize their domain. The tank was set up as a display in the store. When I got home with it I noticed 3 large scratches on the bottom of the aquarium. I'm fairly certain these are scratches and not cracks, I can feel them with my nail but only from inside the tank. With the sheer amount of water that will be going into this tank, do these compromise the tanks integrity? I would be devastated to come home to a blown out tank and more so dead fish...any advice?
