Is my tank failing?

[Boochika]

For the past week or so I've noticed one side of my tank has glass protruding less than 1/16th of an inch from the forward glass. I've never noticed this before but it could have always been like this. I've moved this tank twice now and could be an artifact from that or something else but I'd like the community's input.

The tank is very close to perfect level, the bubble is completely in the center of the level and if anything the low side is the other side of the tank so I would think hydrostatic pressure would be greater on that side. Pictures attached.

How big is this tank?

Tank is an 80 gallon, I believe it's 48 x 18 x 21. I've had it for 2.5 years. It's framed glass with a glass center brace.

looks fine to my untrained eye. If it shifted, there would be some "thing" in the seam that looked off

silicone looks good? no signs of distress?

What I specifically looked at was the frame above and below as well as the silicone. All of it seems to be in good shape. Nothing seems to look 'new' or 'clean' to show that it's been freshly torn or separated. The frame is tight in each location.

Im guessing it was always like that. I see nothing wrong.

I'm going to monitor it for the next month. Taking measurements weekly with my scale. If it grows even a millimeter I'm replacing it.
