Overview

Source reports its Black Morpho-subspecies Hikari family (MLFH × BMA) crossed with Ryu no Tategami; selected blue F2 branch through F4. This profile preserves the claimed history, not a DNA-verified pedigree.

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

Known research gaps

  • Individual sire and dam identification, founder fish registers and genotype tests have not been examined.
  • Phenotype-specific fixation figures from source breeding stock cannot be generalized to retail animals.
  • The cited Japanese source owns or credits its own photographs; none are republished here without written rights.
  • No strain-specific disease resistance, water parameter requirement or feeding protocol is demonstrated; use the separately sourced Medakapedia general-care guides.
