Hi Yee Miau,

Thanks for the advise. And the ranchu is healthy, thanks to you and Nagano-san.


Hi Ho0406,
Well, I am still learning. Probably Yee Miau could give you advise.
Worry that I might give the wrong advise.

I could share with you my own experience and learnings with you:
1) Water is critical, 100% water change is absolutely important as to
maintain healthy ranchu. And also to give the tank some scrub from time
to time, so as to keep the pond clean and free from bacteria/virus.
2) Once ranchu is healthy, 50% of problems solved

3) Japanese has an art of rearing ranchu. In simple term, every day, they would watch their ranchu and see what is lacking and will try to "balance" the ranchu (headgrowth, body growth, tail condition, scale condition) by altering the food, the water condition. I don't think I express this well enough.

What I understand that at the end of the creation stage, a potential ranchu is created by the hand of the rearer. How a ranchu turns out is influenced by the way the fish is cared for (of course, some would argue that it is also influence by the genetic components of the ranchu, I agree to a certain
extent).
