Thanks Simian for sending in this very interesting video.
Two things I thought were of interest - you can catch tuberculosis from a fish according to the video. Does that mean we had better ban fish in HDB flats too because of the POSSIBILITY of disease? After all, maybe some of the water from the fish tank might accidentally come in contact with someone!
On a more serious note, it was interesting to see what advances have been made in veterinary medicine. It's interesting that in most cases, people would probably have been told to get another fish but some owners are going to great lengths obviously because they love their fish a lot.
