I was cleaning the glass on my tank and found a tiny chip. It is round, probably a millimeter in diameter. There are already 3 cracks spreading out from it. I can't tell how deep it goes. It is in the front glass, about halfway up. This is on a 55gal. I'm afraid it's going to slowly spread. What can I do? Is there any fix? I'm already considering going out to look for a new tank, even though I cant afford it and don't have the time to switch everything over. I just don't know how to evaluate how serious the crack is. Is there a temporary solution? Like I can put some silicone on the crack, it will look bad but will that be ok till I get a new tank? I assume once I get everything transferred I can take this to a glass shop and get the front pane replaced. But what should I do right now? Also, does anyone know anywhere to get glass tanks online in about a 55 or 60 gal size? Thanks
