I think so but you're going to have to break out the tape measure on this one. I think you could fit it in closer to the corner, though its a bit tough to see in the pic.
Some rules of thumb for drilling glass. The minimum distance from the edge of the glass to the edge of the hole is 1 to 1.5 times the thickness of your glass for glass less than 1/2" and 1.5 to 2 times the thickness for glass over 1/2". The minimum distance from the corner of the glass (measuring from the point) is 6.5 times the thickness of your glass.
Other rules of thumb I've heard are: at least one hole diameter away from the edge and two hole diameters from the corner. It all roughly works out the same.
Measure it out and see what you think. If I recall, your tank has a 3/4" think bottom pane?
