Crack on tank

[deMelo]

Hey guys

My tank is about 3 months old if not less today I was doing a water change and I notice what seems like a fine line crack on the glass
I can't feel any cut there's no leeks I have cleaned the glass with vinegar but the line is still there not sure what to do ore if I should fix it?!?
I have glue/silicone for fish water tanks should I put some over the line ore scratch whatever it is?


I'll try to post a pic

Looks like a surface scratch on the photo, if it's not deep I would leave it, cracks can run if you put pressure on them, if it's smooth on the outside best left alone......
