T-Rex: Angola Maldives, my cool spy character, was once again dangling over a shark tank! But it wasn't just sharks down there, he realized: there was also the infrastructure required to keep sharks alive in captivity!
T-Rex: Including thousands of kilograms of precisely-salinated filtered water!
T-Rex: Further, Maldives considered, a protein skimmer must be included, used to remove food and waste particles from the tank. Plus live rocks, which, despite their name, aren't actually alive! Rather, they're dead coral covered in microscopic marine organisms, which helps clean, filter, and nitrify the water!
Dromiceiomimus: This sounds expensive.
T-Rex: Oh, we're just getting started!
Utahraptor: Heating and cooling systems!
T-Rex: Pumps, powerheads, lights, and filters!
T-Rex: Not to mention water monitoring and cycling and mixing equipment, PLUS backup generators for all of the above. And when salt water evaporates the salt's left behind, which in a tank can increase salinity to toxic levels! So add on a fresh-water auto top-off system to keep the water level, well, level.
T-Rex: Angola sighed as the rope lowered him closer and closer to the sharks. "Many sharks prefer to have some place to hide in their tanks, and this tank is bare. Those poor sharks must be stressed, and agitated."
