I spent some time observing the fish in Yuan Kheng's house, when I went to train the girls last Friday. She has a huge luohan and extrememly interesting goldfish. Two of the goldfish were face down in one of the corners. The rest of them kept gurgling air at one corner, then presumably they got bored of the scenery so they swam to another corner to continue gurgling air. This process was then repeated several times, and I was just standing there watching them swim back and forth in fascination.

My parrot fish are crazy. Despite the size of the tank, they are still growing. And for some strange reason, they keep arranging and rearranging the stones in the tank, although there I couldn't tell any significant difference from before. Maybe they're just doing maintenence or something.
