AbsoluteRanchu, hope you don't mind but i've a no of questions on Mr Kashino's duckweed: can you pls let me know at what size of the Ranchu does Mr Kashino start feeding his Ranchu with duckweed pls? (bbr, after bbr has changed colour, or when it has reached a certain size?) Does he feed them continuously as they age to oya and beyond? Are all of Mr Kashino's tosai to oya Ranchu fed duckweed once a day? Have you seen the duckweed found in Singapore and is it identical with Japanese duckweed pls? What is the purpose of feeding Ranchu with the Japanese duckweed?

ps from the photos above it seems like either the Japanese duckweed is much finer than the Singapore duckweed, or the Japanese duckweed is pounded into fine substance before using it as a feed?
