Tank Seams

Tank seams on my 40 breeder look like this



I have never seen this on any tank. Could this be a problem? It looks like the glass was pulling away? It's not running the entire length of the seam. They didn't appear until I put water in it the other day. I've had water in it before when I was testing the tank, maybe I just didn't notice.

a friend says that it probably that the silicone had some air in it or the silicone installer may have been running out of silicone. She has seen it before and unless it was really bad I shouldn't worry about it with this small tank.
