How much would it cost to install a tank of sharks underneath a meeting room?

I have a meeting room where I convene with my associates. I would like to install a tank directly below the table and seats, big enough to contain three or four man-eating sharks.
Has anyone any experience in such an installation and what costs am I looking at?

the main thing to consider is the structure, and ongoing costs.

Can you fit a large tank with several thousand litres of water, a few hundred kilograms of sharks and a dynamic load.

Say your meeting room is 10m x 5m, you will want maybe 3m of depth for the sharks. this will give them 150m^3 of water.

Now the tank: it's not as simple as just digging a hole. You will need to put in a concrete reservoir under your meeting room, then reinstate the floor and probably the roof too.

you will need to get a digger of some sort in, concrete pouring, a builder, a painter.. I'd say $100,000+, in addition to losses due to your meeting room being out of action for a good 2-3 months.

On top of that, you will need to source some sharks, transport them in safely.

Your ongoing costs will be maintenance of the tank, the pump, filter, salt, food will be a biggy and finally you will have some sort of insurance liability for storing 3 or 4 deadly killers under your floor.

I'll raise my estimate to $150k+ for the set up, then add $30k per year for ongoing costs.

You are looking at anything upwards of 25k depending on the design, plus you would need planning permission,

The main problems you will find are, running costs, electrical maintenance for trapdoors etc, a cheaper alternative is a smaller piranha tank or just an acid bath

Darling, how unfashionable! We simply have our henchmen to drag the unwanted visitor kicking and screaming to the next room where he meets his fate fist fighting an enormous and hungry american black bear. I find that the sound of grown men screaming and the horror on the faces of his associates as they see their friend ripped to shreads and eaten - well... it was rather exciting to say the least. Although, we still have our old trap door to the shark tank still operatable - I believe that my husband blackmailed a certain young gentleman and we received this tank as a gift... it was fun while the fashion lasted. Ta ta darl'in

I think you are just joshing us, right? If you were serious, I would definitely advise you not to use metal in the tanks as the sharks will bump their heads.
