People sometimes give away (or sell very cheaply) cracked tanks for reptiles and such. You could take the trim off an old one. If it has been this way for a while, you have time to look around for deals on Craigslist and what not.
If you're not a handy person, or don't want to or don't have time to fix it, just get a new tank altogether. It's not that much money, even if it's more than $55.
Bottom line, glue won't fix it...but Colleen's repair will hold indefinitely (such a repair is common), and new trim will fix it too. The choice is yours!
