How long will a glass aquarium last?

I just realized I've had mine for almost 10 years. Is there anything to look for when they fail or do they just let go? whats' the lifespan of silicon? It doesn't look like there's much silicon on the inside of the tank anymore. Maybe from years of cleaning.

If it is filled and maintaied- indefinatly. I have tanks I care for that were started in the
60s- metalframe tanks even. I have a ten gallon I got in 70 that is still fine, and has been wet and dry dozens of times. Likely the older the tank- the likely stronger the build- at least pre late 80s. Silicone would have to be seen to be judged- and that can happen to a new tank with a razor scraper and a few beers.

A long, long time... My dad had a freshwater tank for 25 years. My reef has been setup for 16 years. It is as good as new except some annoying scratches that accumulate over time. No where near as bad as an acrylic tank but, they can't easily be buffed out. This is the reason/excuse for me starting to look to an upgrade.

Reef tanks since 1987.
Current tank: 75g SPS dominated reef tank set up in 1996

if the tank is well glued, I think it will last another 10 year no problem.

the 120 i use as a fuge on my 150 was ancient when I got it around 1990. my new tank was put in service in 1992.

I'll try to be nice if you try to be smarter!
I can't help that I grow older, but you can't make me grow up!

Current Tank Info: 120 mixed reef with 40b sump, ASM G2 skimmer, AI Sol Blue x 2, and a 150g Soft Coral tank with 120g refugium and 50g sump, no skimmer, VHO T12 lights

I know of several people that have had multiple freshwater glass tanks for over 20 years with no problems at all (at least related to the tank itself).

2 55 tanks from '86.

One of the 55 is in my daughter's room no issue.

The other was my sump for a while and the Dell I don't use much because of the scratched glass but the silicone is sound.
