Think dog hotels are odd?
Then you need to check out this “luxury” hotel for fish!
The Nippon Koi Hotel in Singapore offers a full facility catering to the temporary housing of pet Koi. It has 200 ponds, ranging from small to “presidential size”.
The fish are fed and looked after 24 hours a day. There’s even a koi hospital on site. Ponds cost up to $531 per month, though each can house multiple fish. Check out the video below.
One question – how do you tell the fish apart?
