I don't know how this fish tank works exactly, but from what I could understand, the tank on top that joins the adjacent tanks works as a vacuum. The result is that there are feeding holes in the side of the tank, and the water does not flow out. I could not wrap my mind around this technology, but it works.
The fish were swimming between the side tanks over the tunnel. The smarter fish would swim across to the side where we were giving them shrimp.
As you can see, the water stays within the half bowls that are affixed to the side of the tank.
You would think that the water would come gushing out, but it doesn't. In the words of Arthur C. Clarke, "Any sufficiently advanced technology is indistinguishable from Magic.". Yup.
These are all fish that you can find off of the coast of Oita.
This guy got a little carried away and jumped out of the tank. He was delicious!
A brightly colored wrasse goes after some krill and misses. Not the most coordinated fish in the tank...
This rockfish was by far the most tenacious fish in the tank. He boxed out all of the other fish, until he had his fill.
The squirrel fish was a bit harder to lure out.
A trigger fish takes his time, and grazes on a shrimp buffet.
This is my favorite picture of the lot. Puffers, box fish, and cowfish all make me happy for some reason. They're such goofy fish, and tough to boot.
