Otsuka Aka Matsuba | Female | 55 cm
SKU: OGT-AMA-OTS-F-55-2601-045

The matsuba is the whole point

Look at the scales along the back. Every one carries a distinct dark centre, giving that pinecone effect the variety is named for.

What makes this fish stand out is consistency. The pattern runs evenly from shoulder to tail without blurring, patching out or losing definition down the flanks.

That uniformity is the hard part in Matsuba. Plenty of fish show it in one area and lose it in another.

Clean solid head

The head is deep unbroken red with no reticulation creeping onto the face.

That contrast — plain head against a heavily netted body — is exactly what an Aka Matsuba should show. It’s the first thing anyone judging one checks.

Deep warm red

The base colour is a rich, warm red that runs right through the body rather than sitting thin over the scales.

Colour carries into the fins too, which finishes the fish properly. A Matsuba with pale fins always looks unfinished against one like this.

Female at 55cm

She is a confirmed female at 55cm — a substantial fish with real presence.

Size works in a Matsuba’s favour more than in most varieties. Each scale is physically larger, so the reticulation reads clearly from across a pond rather than needing a close look. Females also continue building body volume, and this pattern only gains from that.

Why Matsuba works in a pond

Single-colour koi are underrated by newer buyers and prized by experienced ones.

There’s no pattern to fault and nothing to fade unevenly. What you get is depth of colour and scale definition, and both improve with age rather than breaking down.

Body and finish

Well-proportioned body with good width through the shoulders. Fins well-formed and undamaged.
