 | Maruhide Kohaku | |
 | A female Momotaro Kohaku with a balanced two-step Nidan pattern — and a particularly clean odome (tail-stop Hi), the small separate Hi mark near the tail that breaks cleanly from the main pattern.

 | A female Isa Showa with notably well-developed pectoral tejima — the dramatic Sumi stripes running through both pectoral fins in clear vertical bands. Pectoral tejima is more visually striking than simple motoguro and is one of the most sought-after Showa features, because the dynamic black-on-white striping moves with the fish as it swims, drawing the [...] | |
 | Exceptional scale definition This is the standout feature, and it’s worth looking at closely. The scaling across the shoulder and flanks is unusually well defined. Each scale sits distinct against the next, giving the pale areas a beaded, three-dimensional texture rather than a flat finish. On a Goshiki this is what you want. The variety [...] | |

 | At 45cm this ISA Showa Sanshoku has moved well past the point where a Showa reveals its intentions.
