The customers they have, have almost no involvement with the maintenance, if any at all. It is all hired out to I am assuming their networked maintenance companies. Typically these companies, remove dead fish and replace them same day with the same fish. I am sure the customer knows a fish or multiple fish have died, but when you know absolutely nothing about how the reef actually works, how do you tell the guy fishing them out and replacing them what went wrong. If you don't know why they die, and it is explained as just something that happens with new fish, and you're getting it replaced, why would you even question it? "What do breeding rooms, quarantine systems and procuring the animals have to do with adding bacteria to a tank?" Further, all of these steps indicate a direct correlation between how much effort a public aquarium takes in order to ensure healthy livestock combined with them understanding the biology it takes to make an ecosystem function properly, and taking ALL of the necessary steps to continue on with this pattern of perfection. Why would you spend a huge amount of money to do 80% of it right and then just half ass the rest? It makes no sense whatsoever. I can see the thought process now, "Sure we'll spend 100k to build a display, set it up properly, get quality livestock... but hmm why don't we just get some chemicals, bypass nature, and dump extremely rare fish into a tank that we didn't bother to cycle properly just to save some time." Jeesh, internet detective expert.
