Ginga
Ginga is an improved medaka variety known for the blue-white glow radiating across its back, a shimmer said to evoke a galaxy in the night sky — hence its name. The intensity and spread of this glow vary between individuals and change as the fish matures, making its development part of the appeal. Keeping it well benefits from some prior experience with water quality management, so it is generally considered suited to intermediate keepers. Ginga typically lives 2 to 3 years and reaches an adult size of about 3 to 4 cm, and like other improved medaka varieties it can be kept either outdoors or indoors. Watching its ethereal glow develop is one of the quiet pleasures of raising this fish.

7 things to know before welcoming a Ginga
1Glow Varies by Individual
The glow on a Ginga's back doesn't appear with the same intensity or spread on every fish. Its look can also change as the fish grows, so a young medaka may look quite different once it reaches adulthood.
2Best for Intermediate Keepers
Beyond basic medaka care, Ginga benefits from stable water quality management to keep its glow looking its best. It's a variety best suited to keepers who already have some medaka experience.
3Suitable Outdoors or Indoors
Like other improved medaka varieties, Ginga adapts well to outdoor containers or ponds as well as indoor aquariums. Its glow is often said to stand out more vividly under natural sunlight.
4Avoid Sudden Water Changes
While medaka are known as hardy fish, sudden shifts in temperature or water chemistry can still stress them. Change water gradually, and watch your fish closely during seasonal transitions.
5Choosing Tankmates
Ginga has a calm temperament and generally gets along with other medaka varieties of similar size. If you want its glow to stand out clearly, keeping it in a single-variety group is also a good option.
6Glow Develops Over Time
Many young Ginga show little glow at first, with the shimmer becoming more pronounced as they mature. It's a variety that rewards patience in watching it develop over time.
7Prepare Before Bringing One Home
Setting up an acclimation container and a stable water environment ahead of time helps reduce stress after bringing your fish home. Choose a container size with the adult size of 3-4 cm in mind.
