Can someone tell me if I should be worried by this. Its not gotten any bigger since I got the tank two weeks ago but I got this tank second hand and noticed soon as I got it. Done a little reading in to it and I think it could be a bad seam it's on the front right hand side of the tank and this is the only place its in. I'm no good with things like this so I could be wrong but I'm guessing it is a bad seam.
