I would pay for fish tank that is about 2 fee wide but the whole side
of my wall. I'm talking about 10 to 15 feet long, 9 to 10 feet tall
depending on the size of your wall. Somehow we have to get the oyxgen
in the tank (like a CO 2 injector) so it can support more fish with
the relitively small surface area. Imaging that you come home and the
sight of a whole wall with swiming Discus! I would pay really good
money for that! Water change needs to be automated for sure :-)

Out of curiosity, how would you maintain the bottom of a 9-10 foot deep
tank? I think public aquaria usually have scuba divers scrape algae
and clean the big tanks, but they're usually more than 2 feet wide.

Oh oh oh, I know the answer ) (push over fishlover ;~), at least I have
an idea for it. There is an indent in the bottom of the
tub/mold/tank/container. Ordinarily, nothing is in there, but it could
be large enough to have a potted plant or some type of structure with
caves. When you have to do serious maintenance, you remove anything
which is in this indent (or false bottom), and drop the water level
(taking all the fish with it into this section).

The drawbacks are that live plants on the upper levels would be exposed
to air (so they would have to be robust or don't have live plants in the
upper tiers), and you need a sizable holding tank to hold the displaced
water until it is returned. In fish rooms, I've seen these holding tanks
attached to the ceiling. For other installations, (large built-in
aquariums), the holding tank could be located in another room (preferably
directly above or below the main tank).

Alternately, use the holding tank, but no indent in the main tank and
never take the water down too low.

sorry fishlover, my enthusiasm curbs poorly, your turn.
