can driftwood touch the glass?!?

[hbeth82]

Bought a rather cool piece of driftwood a while back, kind of a tri-pod shape, and after 9 months of soaking, tannins are almost gone & it finally sinks. Plus, I now have 55 in which I think it would look really good. Only problem is that it barely fits in the tank - I can balance it so that none of the ends touch the glass but if I think of sneezing, part of it tips a bit. No weight is really resting against the glass so it's not as though something is being propped against the side of the tank, it's just touching.

This may sound paranoid but is this ok? Doesn't seem like it's applying any more pressure than the gravel or the water but kinda makes me nervous. I can post pics if that would help.

Thanks!
