HELP MY TANK HAS A CRACK. I just noticed a small crack near the corner of my Aqueon 14 gallon rimless cube. I will attach a photo. It does not seem to reach the corner but I can feel the crack from the outside. I’m wondering if this is an immediate emergency that has compromised the integrity of the aquarium. I’ve already concluded I will likely have to tear down the tank. Please help if you know anything about rimless aquariums or cracks.
