Koi and Grass Carp pool

This does look awkwardly like a flooded bathroom, but I think it is meant to represent a Chinese temple sort of thing. This pool (which is larger than it looks in the photo) houses Koi Carp Cyprinus carpio [C. rubrofuscus] and Grass Carp Ctenopharyngodon idella, while a similar pool opposite houses Goldfish Carassius auratus.

This reminds me of one of those liminal space pictures

Reminds me of a public toilet
