Aquarium Sink

That is fish abuse. The whole bathroom would stink if you didn't keep the tank clean. There does not look like there is a way to put a filter or aireator in there. It would be a constant problem. Also, there are two caps on the counter top that come off for feeding. *Any* soapy water that happened to drip in there would kill the fish immediately (soap is a surfactant that affects their gills, and they literally drown). Bad, bad idea. Bad idea. Can't tell you how bad an idea it is to have fish in your lavatory?

@AntDude & LisaL -- the top can be removed for cleaning.

It's a death trap.

1) Oxygen exchange would be virtually non-existent. The surface movement created by the powerhead is pointless if the surface is not exposed to open air. Any fish you put in it would slowly suffocate to death over a period of days. If they even lived that long, because...

2) Tropical fish are extremely sensitive to rapid temperature changes and are only healthy within a very narrow band of a few degrees. There would be no effective way to regulate temperature in this "aquarium," since every time you used the sink it would act as a (forgive me) heat sink. The constant fluctuation in temperature would stress the fish, causing either disease and loss of appetite or killing them outright. But that may not have time to happen either, since...

3) When in a compressed water column with little or no cover, most tropical fish will go into hide mode. This is because they feel exposed to predators. They'd probably congregate in the corners (making it even harder to breathe in the already oxygen-poor water) and would likely refuse food, again leading to starvation, disease and eventual death.

As I said, a death trap. NEAT-or-AMA?

Where's the filter? And as AntDude said... how are you supposed to clean it?

Convenient for when you need to flush the dead ones away.
