Impossible fish tank does the impossible

[X-Tank]

Saw that tank a while back. It's an optical illusion. The tower portion of the tank is actually 2 tanks. The front tank is sealed at the surface. There's an open rear tank that houses the decorations and the air stone. Take a look at the rear glass bottom seam and you'll see what I mean.

Thanks for your explanation..... , ... , but still ???

there is another tank here, this one you can fish comes in and out as well plus the side view with air bubble and decoration.

Please look at minutes 3:18... that tiny purple fish actually went behind the wood.....
at 3:42 that exact same purple fish swam out of the tower tank to the outside tank.
Does that mean the entire system is actually one connected unit??

The only way I can think of that this works (I'm an engineer) is that the air pump draws only from the air space at the top of a sealed-top tank.

unreal

ok i have a question bout the 1st tank.....
wont the fish jump out through those holes? they have shown pics of fish poking their head out so isnt that a possibility?

 

[Oddball]

Of course it's possible. I figure it's highly probable considering the reflex of reef species when they're touched from behind by another fish.

I want to know how they get the water in there initially.

I'm surprised no kid has poked out one of fish's eyeballs with their fingernails yet

Probably the same way I used to remove air from a bridge tunnel between 2 tanks. Place a hose in the tunnel and apply suction (it'd be a good idea to add a check valve to the line in case the pump fails or stops drawing before enough air is removed). I used an overhauled lab suction pump. Remember to keep adding water to the lower tank to maintain a water barrier. The larger/taller the sealed vessel, the greater the amount of suction required to remove all or most of the air.

I think the air stone just pumps the same air from the top of the upper tank constantly, so that it's not adding or removing air from the upper tank.
