end

of

dorsal


fin

both


sides


of
the

fin).


The


second


type


has

a

row

of


scales


beginning


where


the


head


meets


the


shoulder


and

running
the

entire


length


of


the


fish

(along


both


sides).


The


third


type


is


the


same


as

the


second,


with


the
addition

of


a

line

of


(often

quite

large)

scales


running


along


the


lateral


line

(along


the


side)


of


the


fish,
also

referred


to


as

"Mirror


Koi".


The


fourth

(and


rarest)


type
