Temperature

18〜28℃

Diet

Prepared medaka food, green water

Lighting

External luminescence and lame appear on the dorsal side and read from above, while the red in the fins can also be judged from the side. The Medaka Web Encyclopedia recommends outdoor keeping and suggests shading half the container in summer.

Diet & Nutrition

Commercial prepared medaka food is the staple, given in an amount finished within a few minutes. Leftovers decay and foul the water, so adjust the quantity. Green water rich in phytoplankton suits fry rearing.

Water Temperature & Quality

Slightly acidic to slightly alkaline water is considered ideal, and the water drifts toward acidic as keeping continues. Around one water change per week is the guideline, and because sudden shifts in temperature or pH cause stress, acclimatise new fish by floating the bag. FishBase records the wild water chemistry of this species as pH 7.0-8.0 and hardness 9-19 dH.

Tank Mates & Compatibility

A peaceful schooling fish, normally kept as a group of the same variety. One litre of water per fish is the guideline against overcrowding; overstocking causes poor growth, reduced breeding, oxygen shortage and water fouling.

Breeding

Outdoors the spawning season runs from about April to October, once water reaches 18C or above with 12-13 hours of daylight. For year-round indoor breeding, 25-28C water and over 13 hours of lighting are the guideline. Eggs hatch at a cumulative 250 degree-days, about 10 days at 25C.

Health & Notes

Selection has to weigh the tricolour pattern, the lame and the fin colour at once, so numbers are needed. Semi-transparent scale does not separate white and black as cleanly as transparent scale, so confirm the scale type before judging the pattern.

About Reiwa Tricolor Lame Miyuki Medaka

Reiwa Tricolor Lame Miyuki Medaka pairs Miyuki's shine with a tricolor, sparkling lame pattern and red-tinged fins. Here's what to know before keeping this advanced-level variety.

7 things to know before welcoming a Reiwa Tricolor Lame Miyuki Medaka

1. 1Best for Experienced Keepers

   This variety combines traits from multiple lineages, and keeping its coloring and lame sparkle looking their best takes some experience. It's a good idea to get comfortable with a hardier strain first before taking this one on.

2. 2Highly Individual Coloring

   The mix of white, black, and orange, along with the placement of the lame sparkle, varies from fish to fish even within the same brood. Watching the pattern shift as each one matures is part of the fun.

3. 3Fins Keep Their Red Tint

   Thanks to the "Reiwa" lineage, the fins hold onto red pigment more readily than a standard Tricolor Lame Miyuki, whose fins often stay pale. That fin coloring is one of the things worth watching for.

4. 4Lame Sparkle Shifts With Light

   The lame scales catch light differently depending on the angle, so sunlight or aquarium lighting placement can change how they appear. Adjusting the lighting in the tank helps bring out their sparkle.

5. 5Adults Reach About 4cm

   Fully grown adults reach a standard length of up to about 4cm. It's worth choosing a tank or container with enough room for that eventual size from the start.

6. 6Acclimate Carefully After Arrival

   Improved varieties like this one tend to be sensitive to sudden changes, so take time to match water temperature and quality gradually before moving new arrivals into their tank. A rushed transition can cause stress or health problems.

7. 7Traits Can Separate When Bred

   Because this variety blends several traits together, offspring can end up with the tricolor pattern, lame sparkle, and red fins showing up separately rather than all together. Maintaining the full combination takes selective breeding over multiple generations.

Frequently asked questions about Reiwa Tricolor Lame Miyuki Medaka

Q.Can beginners keep this variety?

A.This variety is generally considered better suited to keepers with some medaka experience. It's a good idea to get comfortable with basic water quality management first.

Q.How big does it grow?

A.It grows to a standard length of up to about 4cm. Choose a tank or container that leaves enough room for that adult size.

Q.What does the "Reiwa" name refer to?

A."Reiwa" is a nickname referring to translucent scales and fin beauty, and it helps red coloring show through the fins more readily than in a standard Tricolor Lame Miyuki.

Q.Can it be kept with other medaka?

A.Its calm temperament makes mixed-tank keeping with other medaka possible. That said, keeping it as its own group makes it easier to appreciate its coloring and lame sparkle clearly.

Q.Will offspring keep the same traits if bred?

A.Since this variety combines several bred-in traits, offspring often show the tricolor pattern, lame sparkle, and red fins separately rather than all together. Stabilizing the full combination requires selective breeding across generations.
