Hi,
The fish is a splendid Hikari-moyomono, It's body shines with platinum, which makes this brown fish bright.
The platinum shine on the back and fins, and detract enough to judge this a fine Hikarimono.
Further, the brown color is elegant, and the fine Doitsu scales are neatly aligned. The pectoral fin with brown stripes makes this fish outstanding.
I would call it a Platinum Cha Doitsu, or maybe a Doitsu Platinum Ochiba Shigure?
Ek hou baie van die vis. Geluk!
