I think an Aquarium Wii channel would be too awesome, and I really, really hope we get something like that in the future - even as a WiiWare title. I more easily pay a few $ for it. (are you listening Nintendo???)

Some potential features:

 - breed your fish
 - use WiiConnect-24 to send/trade fish with a friend
 - take screenshots, and send to people
 - use the Wiimote to shine lights, poke the fish, feed them and more
 - buy/collect objects and decorate your tank
 - uses the realtime clock to work out the fish cycle, how much daylight is present

You could get money for daily feeding, trading with others, selling items/fish, cleaning the tank. A more elaborate version could have bigger user content generation tools.

The money is used to buy new fish, trade, new items, upgrade your aquarium and more.

It would encourage daily play, trading and a bit of creativity.

...

I also can't imagine how cool it would look on my new toy (TV...). We would probably just leave it running all the time. 

Any thoughts? Anyone else want something like this? It could also be a awesome feature for something like HOME - Sony may already have it planned.

Wouldn't be my cup of tea but I could very easily see my aunt mother and sister all dying to pick up a game like that. Nintendo should get cracking on it before someone else does or like you said 3rd parties on WiiWare gogogo!

If it were free i'd use it..

you could leave it on during the afternoon so it feels like a real aquarium.

Even though burn-in is rare on newer HD-TVs, I still don't feel comfortable with the current Wii diming as a screensaver.   Don't you just hate when you aren't near a save point and your phone rings?  Perhaps an aquarium could act as a Wii screen saver.   You can fill it with the fish you catch in Animal Crossing, Zelda, etc.  Perhaps a Blooper from Mario, a dead Tataglia from Godfather, or a metroid could float through on occasion. 

That sounds AWESOME! I would buy that.

Wii-quarium, eh? I'M SOLD!

Sounds like an aquatic Viva Pinata, which is not a bad thing. I actually have an aquarium screen-saver that's very soothing. It would rock as an interactive feature.

i would buy like a hundred fish then stick a piranah in it. :D

Dude, I would totally buy a Wii Aquarium. That's friggin awesome
