Typically, 55G are tempered glass, at least the bottom pane...

Best way to find out is to call the manufacturer, or if you have a pair of polarized sunglasses you can use them to see if its tempered.

When It comes to unknown tanks take the safe route and drill the back. You can also tell if its tempered by tapping and scratching.
