should I worry about this?

I've spotted these little bubbles in the silicone in my tank, I have never seen them before but I guess I haven't been 'looking' actively for them before. What do you guys think?

I think that is just air bubbles that got trapped when the silicone was applied

Ive had those, didn't seem to do my tank any harm!
