these buggers were in a man-made pond in the tampaksiring temple and they were ginormous. i soon learned why when a man came to offer me fish food to give them. i declined but chatted with the guy for a minute and found out that despite their delightfully plump appearance, koi fish are no good to eat. BUT there was a type of fish in there among them that is quite good, though not as large. be sure to make a note of that.
