Strain Notes
Mega Rayquaza is a modern Japanese collector medaka associated with Medakaya Savanna / めだか屋サバンナ. Aquaphoria does not advertise an unverified breeding formula or parentage for this strain.
Expression can vary between individuals and with lighting, age, viewing angle, and container color. Metallic shine, darker patterning, and cool-toned reflections may differ from fish to fish.
Care
Temperament: Peaceful
Best setup: Medaka tub, patio pond, planted aquarium, or breeding setup
Viewing: Especially suited to top viewing
Diet: Appropriately sized quality medaka pellets or micro pellets, with foods such as baby brine shrimp or daphnia used as suitable supplemental foods.
Maintain stable, clean water with gentle filtration or aeration and avoid sudden temperature or water-parameter changes.
Please read the Shipping & DOA Policy before ordering live fish. By purchasing, you agree to the arrival documentation requirements in that policy.
Strain traits, history & competition record (Aquapedia research)
- Traits to look for: Darker metallic Rayquaza-type fish with scattered guanine/lamé reflections; expression differs between individuals.
- Reported lineage / breeder history: The base Rayquaza is documented as Neptune × Metallica Wide Fin. A Rayquaza × Kurogoromo Earth Eye ancestry for Mega Rayquaza was reported in a historical trade channel, but is not breeder-confirmed, so the exact Mega pedigree remains unverified.
- Created / released: Base Rayquaza released August 2024; this is NOT a verified Mega Rayquaza origin or release date.
- Competition awards: 1 documented placement: Medakaya Savanna entered Mega Rayquaza in the top-view division at the 3rd All-Japan Medaka Competition (May 25, 2025), receiving the Excellence Award (優秀賞). This documents one named-strain award, not an exhaustive lifetime total, and does not establish that the individual fish sold here were the award-winning specimens. Competition results (Kamihata).
Research distinguishes documented breeder statements from unverified commercial names. Individual animals may vary, and a strain's history does not certify this stock's exact parentage. Sources: Base Rayquaza history and August 2024 release; Savanna original catalogue — base Rayquaza. Evidence reviewed October 2026.
