Liberate your goldish.

Might check with your local DMV...

If you’re the type of person that feels bad about keeping your dog inside all day, consider the plight of the common goldfish. Tiny tank. Terrible memory. Same thing for every meal. For most of your average goldfish’s life there’s not a diversion in sight, and even if there was, he wouldn’t have any way of checking it out. It’s not like his fish tank is on wheels.

Unless it is.

Thanks to the folks at Studio Diip, a Dutch company specializing in image recognition, one lucky goldfish is enjoying just such accommodations. Granted, the mobile home is basically just a cheap aquarium on a RC car chassis, but the fish is indeed at the wheel. A camera mounted overhead tracks the direction it’s swimming and steers the car accordingly.

Goldfish: the world's most underrated pet. I had goldfish in my first aquarium. Well, maybe it was the second, after I learned that neon tetras are not as hardy as one might wish. And then over the years they moved from 3 to 6 to 12 to 20 gallons. By this time they were reduced from 4 to 2, and then the female died and Mojo was left all alone. (I named them after a neighbor's four cats.) So I had to get him a new roommate. He was so happy and excited! It was just like when someone new moves into the rat cage.

I don't understand the moving aquarium. The fish still runs into the glass, doesn't it? Unless there's concurrently a sort of jacuzzi-treadmill arrangement so it can keep swimming forever. (Rosy barbs would like this. You wouldn't think it to look at them because they're a bit squat and dumpy-looking, but they love a big tank.)

The two goldfish continued growing until finally I rehomed them to a pond. afaik they're still happy and healthy. And then their tank became my brackish tank-- mollies and a red-clawed crab-- while the former brackish tank went to saltwater.

And that's all I have to say about fish ;)

With the hamster balls¹, the hamster gets to control where he goes, after a short learning curve (and barring any cats/dogs/small children that may have other ideas). It would be way more cool if the RC was interfaced with sensors that detected the orientation of the fish and changed directions when the fish changed directions.

THEN the cat would need to watch his back!

¹For those who don't know, these are clear plastic balls that you can put your hamster/gerbil/mouse/whatever in so he can roam around the house and not escape. Until he slams into the wall hard enough to loosen the lock...

It is a myth that that have bad memories. They have memory-span of at least three months.

And if you want to stop them growing, leave them in the tank, as it stunts their growth. In the right conditions, they will grow to over a foot.

I hope you are not seriously advising this.

The drawback to hamster balls is that hamsters have no brains. So every single day they get stuck in exactly the same place and sit there forever until you notice and rescue them. If you have a piece of furniture that's just one millimeter shorter than the hamster ball, that's ideal. A good second choice is a lamp cord lying on the floor in a corner, or a similarly positioned area rug. They can zip over it, but can't get back out.

It is shocking that cats have such a high PR on the web. Goldfish have rights too.

It is a fact. Simple as that. Don't shoot the messenger.

If you put a baby shark into a standard size aquarium, it will outgrow it. Goldfish are different.
