Bubbles in silicone joint, paranoid?

[Demasonian]

Hey,

Okay, so I've recently completed a fishless cycle and I'm readying my first  tank for its inhabitants (not yet purchased), when I notice a series of mushroom cloud-like bubbles extending from the outer edge of the right side of the tank. I don't know if they're new or have been there all along, but I've never noticed them before. I've attached a photo of the situation.

My question is, is this a problem? Should I monitor it for awhile to see if these bubbles are expanding and live with it for a bit or should I be replacing the tank itself ASAP? The tank has been running for about 45 days.

Help.

It's not actually air bubbles.

The joint has been yanked a bit out of place.  Not uncommon to see something like this on a new tank that is not 100% level.

I had a 75 gallon that did that ... I returned it simply because of aesthetics.

Thanks BD. I appreciate your response. If it's purely an aesthetic defect, I can live with it.

As an aside, I thought this bloody hobby was supposed to be relaxing...If I keep having apocalyptic visions of exploding tanks, I may just resort to having an aquarium screen saver instead.
