Official JMA record
Nickname: ブロークンデビル(クリスタル) / Broken Devil (Crystal).
Official variety name on the JMA recognition header: 未定 (undetermined).
Application field labelled 品種名: ブラックラメクリスタルロングフィンアースアイ; preserve this as applicant-submitted terminology, not as a finalized official JMA variety name.
Supported lineage
JMA states that No. 41 was developed by successive breeding of individuals showing a strong クリスタル expression that appeared from the variety デビル (Devil). This supports a direct parent-line relationship of
デビル → selected strong-crystal individuals → ブロークンデビル(クリスタル).
The application describes black body color carrying white pigment plus guanine crystals, with side guanine associated with Earth Eye (アースアイ).
Terminology boundary
JMA explicitly says the rough/granular crystal phenotype lacked an established trait term at application time, so the applicant recorded it as クリスタル. The 2025 JMA classification manual later adds the trait term パウダー, but the reviewed primary source does not explicitly equate No. 41's クリスタル with パウダー.
Therefore クリスタル = パウダー remains UNVERIFIED and must not be normalized as a synonym without a later breeder/JMA statement.
Counting rule
Count No. 41 once as one officially recognized improved-medaka entry. Do not separately count ブラックラメクリスタルロングフィンアースアイ, ブロークンデビル, and ブロークンデビル(クリスタル) as three strains; they are application-field/nickname representations attached to the same JMA recognition record.
