Back when I was in university, I often went for walks at Fish Village in Ratchaburi. The place was filled with pets and plants for sale, though fish and aquatic plants were the main attractions.

While browsing the fish, my attention was caught by a huge fish in an aquarium that was barely large enough for its body. I felt sorry for it. It must have been very uncomfortable living in such a confined space, but there was nothing it could do about it.
