Repairs

So, quite by chance I ended up with a Blotched Tiger Salamander, which I'm trying to keep and care for. I was given a used aquarium that was just in storage at the high school. When I was cleaning it up, I discovered a crack near the corner, low down on one side. Is there a product can I use to keep it from spreading? Hopefully you can see it from the pic

It would be easier and better to go onto youtube where there is a few videos on how to repair aquarium glass.
