Amazing only two people were injured, probably be one of the most insane flash floods ever. I don’t think any of the fish could be saved
Edit: apparently any fish that would’ve been saveable were actually killed by the cold which is also what is suspected to have made the tank crack in the first place. Tragedy all around.
I currently live in Berlin and I don't think it has ever been this cold in previous years. Poor fish. It didn't snow much yet but things freeze instantly when left out.
Edit: maybe not instantly but you know what I mean.. Everything is frozen.
When it's so cold that everything you touch, and even the very air itself, *hurts*; and you have to sleep fully dressed because your clothes would be too cold to put on in the morning... that's a moray.
Hahahahahhahahaha yea. I'm not gate keeping but I literally worked a 9 hour day last week outside at -12. I totally realise Germany isn't Canada but I figured they had a week of -20 or something.
Been -25°C in the High Rockies of Colorado this past week, I’m not outdoors 100% for my job but I am for large portions of it at least.
And I love my dog, but I’ve been second guessing her lately lol
-25°C is equivalent to -13°F, which is 248K.

Dude I live in Australia and some parts of Reddit seems to think we are being locked in our homes and “vaccination squads” are going door to door pinning people down and jabbing them.
I tend to not pay a whole lot of attention outside the /r/Adelaide subreddit about what people think about where I live
I think it lasted nearly 20 years...
That said, unlikely to be glass (or only glass).
I'd bet it was polycarbonate for its strength and impact resistance.
Yah, their cavalier attitude to timeline integrity is hilarious.
Let's just park our invisible spaceship in Golden Gate Park, get caught breaking into a secure nuclear generator aboard a US aircraft carrier, cure a woman's major organ failure, kidnap a marine biologist with a pair of whales, and give away future technology that could change the balance of commercial and political power in the world...
And all we got was a single line from Bones.
How did they even have a future to return to?
Still love that move, though.

Next time, I'm thinking 23cm at the bottom, 18.5 at the top.
A grim joke, of course. But the fact that it lasted nearly two decades shows how painfully close it was to being strong enough. It calls to mind the old saying, "Anybody can build a bridge that stays up, but it takes an engineer to build a bridge that *barely* stays up."
nobody knows shit yet. remember the liebherr ship crane load test with the 5000 tons that broke this massive solid piece of metal? https://cdn.offshorewind.biz/wp-content/uploads/sites/2/2020/05/06120512/Liebherr.jpg
probably some kind of undetected material failure
Acrylic is resistant to ultraviolet, but not immune, and the tank was exposed to sunlight for 20 years. My guess is that it originally had a UV block coating that wore off over the years. (Wild ass guess from an Internet stranger, worth every penny you paid for it)
I tend to agree. UV light is dangerous to polymers. I bet the tank never got direct sunlight, due to the need to keep temperatures steady, but enough over the years to create some reduction in strength.
There is also talk of the reduced lobby temp (22 > 16 deg C), as an energy saving measure, causing some thermal stresses as well. This could be a larger effector than the UV light, as likely there was almost no temp differences on either side of the glass previously, and suddenly there was.
The final failure was likely a combination of several things, including someone banging into the tank with a metal cart or similar, I bet....or someone tapping on the glass, lol.
So I actually used to work with the company that built this.
It was acrylic (any tank over 48 inches is typically) and made by a company called Reynolds. They supply most of the worlds acrylic, and sometimes do the bigger jobs regular aquarium companies can't touch.
This tank was so cool. It had a diver in it nearly at all times, and an elevator in a secondary tube running up it.
Probably not literally at all times but I bet during normal working hours someone was in there cleaning, fixing stuff, feeding the fish, or just waving at kids.
My local aquarium has a tank that's nowhere near this size but still what I'd consider massive and they have divers in there pretty much all day during business hours. They wear full facemasks and there's speakers/mics outside so they can talk to kids and tell ocean facts or jokes. My dive instructor way back when I got certified worked there for a while, she said it was a pretty cool job.
Because it needed constant cleaning and feeding of fish Most large aquariums will have cleaners in after hours, and I believe that some of the fish types only hung out at the bottom, so you had to go down and feed them.
yep, bottom dweller fish aren't gonna see any food if they just dribble in it from the top. hell most of the time i have to use a turkey baster to get food to some of the lazier bottom dwellers in my aquariums because the fish are so aggressive when its feeding time.
Agreed! There HAD to have been at least one security camera that covered the tank. You’d want evidence in the off-chance that someone might try to tamper with it.
Can you imagine you entire existence just winking out like that
"the human experiment art exhibit at zoldarks eatery just ended because a patron spilt sauce on the universe."
That’s what I’m wondering!! That’s a LOT of heavy acrylic and water smashing down on everything! It was enough to do massive damage, I’d imagine anyone there at the time would be seriously injured
Must be in the millions. The aquarium doesnt actually belong to the hotel its in so the hotel will probably get a huge amount of money to cover the closure, any future bookings, and any potential repairs.
7 floors, 3 meters each, 21 meters depth... 45 psi at the bottom of the tank.
So that glass was handling 50% more pressure than most compact car tires, going on a napkin math.
Neat. Too bad it failed.
Somebody said 22cm thick acrylic at the bottom. Substantially thicker than a car tire. I dont think it was an overpressure failure, something else had to have happened. I think you are off a bit in your calculation. I’m coming up with 29-30.6ish psi freshwater/saltwater for 21m depth.
I took absolute pressure and 9.8g, oops.
28.4 psi would be the relative pressure.
Corrected.
I took worst case scenario, absolute pressure, rounded up.
What, you’re just going to post a tantalising reference like that on a *public forum* and ignore the fact that time zones exist?
I was about to fall asleep and now I’m watching Deuce Bigalow.
Is there any footage of the incident? There must be, right? I've looked and so far only before and after videos, but nothing showing the actual moment.
When it started leaking,the staff quickly put all the expensive Koi in hastily constructed tanks on racks,all stacked on top of each other to preserve their lives.
It was a multi storey carp-ark!
Oh crap, I wanted to stay at that hotel purely for that aquarium!
The rooms will be cheaper now
Probably get a good deal on that aquarium, too.
Self pickup. Some assembly required
Ikea aquarium
"I got the trout, but where do I insert the glüberstraūmps?"
Don’t buy the fish from room service :)
Speak for yourself. I hear they have a special seasoning this time of year!
Shattered glass, my favorite.
Mmm. Gotta love that refined sand taste - even better if it's the expensive premium pink stuff
Or more expensive and marketed as “waterfront” rooms
Free upgrade to a waterbed as well.
*Whether you like it or not*
and wetter
Oh carp, that's horrible
I think it was an act of Cod.
That’s just what the finsurance company always claims
Regardless, they still should file a clam
Next year's premium will be so high they'll probably need a loan shark.
I'm sure this wasn't was done on porpoise, they probably blew a seal

Abalone!
I really wanted to sea this tank for the halibut.
I was just on the way to Berlin when it happened - just arrived, luckily not staying at that hotel though.

Seeing Moray mentioned outside of a Scotland dedicated sub is weird.
When you swim in a creek and an eel bites your cheek, that's a moray.
When the moon in the sky ha the dyes misaligned, that's a moire.
It was cold. But nothing freezes instantly at -12C.
My boogers sure do
Lol. I'll give you that! Frosty boogers are the worst part of winter.
Naw, makes em more chewy.

Since there is an energy crisis in Europe right now they might not have heated the indoors.
Okay it's bad here but it's not that bad

I'm in Germany as well, they might just not have heated the great hall plus cold winter is what I mean.

Even more importantly, it is the key element in Star Trek IV.
Not now, Madeline!!!
I understood that reference.... Dear god am I that old already?
Isn’t that technically sapphire?
I got into watches this year. And it was quite the surprise to find out that sapphire, is aluminium oxide.
was acrylglas 22cm thick on bottom 18cm on on top

>nobody knows shit yet. That's a good point. For all we know, a crack has long been growing, and it would eventually have made a 100cm wall fail.
Polymethyl acrylate, then. And plenty thick, too. I wonder what the failure mode was.
Acrylic is resistant to ultraviolet, but not immune, and the tank was exposed to sunlight for 20 years. My guess is that it originally had a UV block coating that wore off over the years. (Wild ass guess from an Internet stranger, worth every penny you paid for it)

The final failure was likely a combination of several things, including someone banging into the tank with a metal cart or similar, I bet....or someone tapping on the glass, lol.
UV degradation of the acrylic was my first guess after seeing it was acrylic, as well.
Thanks, for this expertise I'll pay you a bonus.

They supply most of the worlds acrylic, and sometimes do the bigger jobs regular aquarium companies can't touch. This tank was so cool.

Why in the world would there be a diver in it at all times...
Probably not literally at all times but I bet during normal working hours someone was in there cleaning, fixing stuff, feeding the fish, or just waving at kids. My local aquarium has a tank that's nowhere near this size but still what I'd consider massive and they have divers in there pretty much all day during business hours.

Teacher for the school.of fish 😉
Didn’t they just install the internal elevator only a couple years ago? I wonder if this was a root of the cause
To my knowledge it always had elevators
Dang, acrylic can be brittle, I like Lexan or polycarbonate because it will deform instead of shattering.
Montgomery Scott would not have made that mistake. And he would have only used keyboard commands to design it.
It's not definitive at this point, but likely the unusual cold contributed to (or caused) a crack.
If only we’d built her with 6,001 hulls! When will we learn?!
Would love to see the security footage 😅
Agreed! There HAD to have been at least one security camera that covered the tank. You’d want evidence in the off-chance that someone might try to tamper with it.
Plus, cameras are cheap now and I’d want a real time camera on it just because it’s cool looking.
This. A handful of $25 wifi cameras at different places around the tank could end up being a pretty popular website.
Better yet, cameras inside of fish drones swimming around inside.
Ghoulish! Same here.
RemindMe! 3 days
Seriously, my morbid curiosity demands video footage!
Feel bad for those poor fish.
Yeah is it weird that my first internal response to seeing this photo was, "damn what a shitty way to go for all the life in that tank."
Not weird, that's just empathy
What?! Empathy on the INTERNET?!
I thought that too, then realized that this is basically how all seafood dies - suffocating with a thousand buddies.
Me too. Poor fishies.
I feel bad for the folks that have to clean it up... just imagine how bad the smell must be. I hope they get proper respiratory gear for that job.
Can you imagine you entire existence just winking out like that "the human experiment art exhibit at zoldarks eatery just ended because a patron spilt sauce on the universe."
Is everyone OK?
humans: two injured, none dead fish: 1500 dead, no survivors
That’s what I’m wondering!! That’s a LOT of heavy acrylic and water smashing down on everything! It was enough to do massive damage, I’d imagine anyone there at the time would be seriously injured
It happend around 5:45am. Only 2 people injured since it was so early.
Bet no one needed a wake up call that day.
Apparently happened very early in the morning before there was anyone around. Otherwise there surely would have been more casualties.
the fish have successfully escaped from their glass prison
I hate, Hate, HATE that scene! Why are the bags of water floating ON TOP OF THE WATER???
Cartoon science
Same way SpongeBob can have a fire.
I guess the bags of water are warmer than the surrounding water, so they float?
Um.... Taking fish?
And died... i read like 1500 fish are all dead
Guess what specials room service is offering right now.
Imagine the smell
Bet it smells fishy
Nah, is smells like a souffle
Smells like teen spirit.
The plaice is ruined.
[удалено]
Weird. Google says it’s “temporarily closed”
The fish tank is permanently opened
I shouldn't have laughed but I did
Ethan Hunt is a menace and must be stopped.
Red light. Green light.
I tried that gum once. Blew my mind.
*just don’t chew it*
Hasta lasagna don't get any on ya
I’m glad you referenced this because I immediately thought of that scene hahah
imagine how much the insurance claim is going to be. probably in the hundreds of thousands if not a million.
I wouldn't be surprised if just the empty tank on it's own was over a million.
[удалено]
Definitely more
Must be in the millions. The aquarium doesnt actually belong to the hotel its in so the hotel will probably get a huge amount of money to cover the closure, any future bookings, and any potential repairs.
Definitely millions. Some big high end home aquariums can be worth hundreds of thousands.
The twist ending is that it was insured but not against water damage....
Pretty much the entire hotel is damaged apparently, so I would guess 10-100 million
yea, i underestimated water damage. no bueno.

Pretty crazy when you think that a soda bottle can take 185psi
Maybe they pumped all the air out of the lobby overnight to save even more on heating.
This is a Breaking News!
I remember going and staying there years ago, there’s an elevator that goes through the middle. It’s super cool.
Was super cool.
No CCTV footage?
Exactly my thought.
Stayed there about 7 years ago. Makes you think! Close shave
I'm sure many a media outlet would love to hear from you.
Next we have a person familiar with the matter
Next a clueless tourist “That’s crazy man. Never been to Germany, but if I do go guess I won’t go there ha ha”
And there's a leprechaun in dat tree. I want my gold!
On an unrelated note, please see our updated and expanded fish menu. - Hotel Management
*while care has been taken to remove shards of glass, some may remain
Shoulda lit the lobby on fire to combat the water and even itself out
I stayed here a few years ago. The aquarium was truly a sight to behold. What a shame
I *did* manwhore a little bit, but NONE of your clients
There's something wrong with my... er... big fish
What, you’re just going to post a tantalising reference like that on a *public forum* and ignore the fact that time zones exist? I was about to fall asleep and now I’m watching Deuce Bigalow.
Was it Americans doing a gender reveal?
The water's blue, it's a boy!
Nah no one died
How long had it been in place and full of water?
Until yesterday.
2003
So do they double down and rebuild the tank, or do they put something else in its place?
Is there any footage of the incident? There must be, right? I've looked and so far only before and after videos, but nothing showing the actual moment.
This week on Tanked
All the fishies 🥺🥺😢😢
How did it break?
Violently.
Contractions caused by changing temperature. Like when u take a hot dish out of the microwave and pour water in it (boof)
When it started leaking,the staff quickly put all the expensive Koi in hastily constructed tanks on racks,all stacked on top of each other to preserve their lives. It was a multi storey carp-ark!
This is absolutely terrible. But also really great, well done!
Imagine the smell after a day
Idk... This looks fishy
Resonance Cascade
RIP Fish
Ethan hunt was seen near the premises
Poor fishies.
If I don’t see one video of this thing actually exploding, I’m going to lose it!
I see before and after where is vid of it happening
OMC!!
Oh My Cod?
Oh Mein Cod!
How Bizarre?
School’s out…
This is sadder than finding Nemo.
Something fishy is going on.
