What’s that pic shows on my tank
 

My tank is not leaking or having any issue but at one corner shows that mark inside the side glass and the back joint and that too in between the seal from outside and inside. Is that a concern I need to take care now?

Any suggestion please.https://uploads.tapatalk-cdn.com/201...597bfaea1b.jpghttps://uploads.tapatalk-cdn.com/201...6ea7813ee1.jpghttps://uploads.tapatalk-cdn.com/201...d076a1a125.jpghttps://uploads.tapatalk-cdn.com/201...e966599d1e.jpg

Looks like the silicon has partly seperated from the side panel
