Brentwood Mall Tanks ...

[Seriak]

I would say that in most of these situations, they get it in their head that a SW fish tank display would be great, but once the realize the cost of having someone else maintain it or the amount of work to maintain it themselves, they end up letting it become what you see. It could also have been a worker who actually was maintaining it, but they left the organization for whatever reason and now it's left with no one who has a clue on how to keep it going.
