What Is "Fukurin"? Options

[CP]

I have a friend who does not receive much education,but a fish hobbyist nonetheless and owns prize winning kois.I have learnt much from him in terms of fish appreciation.

He always stresses on the importance of "pookoolink".That is what made the scales of the fish shine.Be it koi,discus,arowana or goldfish,"pookoolink" is a must before the fish can be a prize winner.

At Aquarama 2003,he has shown me many examples of prize winning discus and all these discus are rich in "pookoolink".

So I asked him WTF is "pookoolink"? Is it an English word,Japanese or Hokkien?
He doesn't know.All he knew is that it has something to do with calcium,and its like 'match flint'.

I suspect that it may be an English term.Any members heard of it before?

talking koi or talking goldfish har ?

Talking "pookoolink" (Fukurin) on fishes,be it koi,goldfish,discus or aro.

Now we know Fukurin is much sought after in kois,so I wonder how is it that we can groom our goldfish to be rich in fukurins.But we must first learn to spot the fukurin on the goldfish.

From the article posted by Goldrush,it takes a trained eye to recognise fukurin.And according to my friend,fukurin play a very important part of a fish in the beauty of a fish.As I have mentioned earlier,2003 aquarama discus winners are covered with fukurins.And we,goldfish lovers should try to groom our fishes rich in fukurins.
