Lineage review · Batch 028: Japanese specialist documentation describes repeated family selection. These illustrated stages are not a newly proven founder cross, genotype, or dominant trait. Original specialist reference ↗

Lineage review · Batch 015: Original parental pair has not been established from cited material; the illustrated pedigree intentionally retains an unconnected ancestry gap. Specialist source ↗

Overview

The specialist credits Kanbara and describes selection favoring transparent rather than semiflat/translucent offspring from line pairings This is a historical creator/source record, not verified DNA or authenticated current broodstock.

Evidence labels refer to documentary strength. They do not assert independently tested genetics.

Known research gaps

  • Original parent-fish specimen identities, complete breeding ledgers and unambiguous first-sale dates remain unconfirmed.
  • No molecular evidence establishes trait inheritance or the breeding uniformity of retail stock named for this variety.
  • Photographs are source-owned and have not been rehosted; licensing review and photographer attribution are pending.
