Would you be worried?

I just re-siliconed my tank for that reason....although in my case it looks like a little worm got in where there was an air pocket and a pinhole leak started...as long as the bead around the edge is not broken you are ok...monitor the air pockets. Trust me, i called every tank manufacturer i could think of and ask them...in my case i cut out a bit and re-siliconed...not very neat but it is hidden. If you want to drain tank and run a bead along it again...but i have seen tanks like this before that have been running for years. Unless you get a worm...or the silicone dries out i think you will be okay. if you tank is warrantied you may complain, if i bought a new tank with airpockets they WOULD be re-doing it.
