Just a note on reptile tanks: I don't think it will make a difference on something as small as a 10 gallon tank, but it's not unusual for glass reptile tanks to be made of much thinner glass than fish tanks. The thick glass isn't needed for reptiles, where really all it's needed for is just to keep them (and you) safe and to provide a good viewing area, where as with a fish tank it provides the same thing plus it also has to hold back all that weight of the water. I've heard more than one horror story of someone thinking they got a great deal on a larger tank, only to have it develop a crack or break altogether at a later time just because it was a reptile tank.
Sorry, I'm off my little soap box now
