Boukyaku no Tsubasa
Boukyaku no Tsubasa ("Forgotten Wings") is an improved medaka variety with a striking aurora-toned body blending deep black and orange, densely covered in shimmering yellow glitter scales. Its defining trait is combining long, flowing fins with rich glitter — a pairing that's notoriously hard to achieve, since fin length and glitter density often work against each other in breeding. The result is a fish whose elongated fins ripple gracefully as it swims, catching the light and setting the glitter aglow. Adults typically reach 3 to 4 cm in body length and live around 2 to 3 years. This variety is considered suited to intermediate keepers, as maintaining its coloration and fin quality calls for some hands-on experience — but that makes it all the more rewarding to raise.

7 things to know before welcoming a Boukyaku no Tsubasa
1Managing Fins & Glitter
The long flowing fins are prone to damage from strong water flow or contact with tankmates, so consider current strength and compatible tankmates carefully. Keeping the dense glitter looking its best also calls for stable water quality and avoiding sudden changes.
2Best Suited to Intermediate Keepers
Boukyaku no Tsubasa is considered an intermediate-level variety. Coming in with some experience in basic water quality management and daily observation makes it easier to maintain its coloration and fin beauty over time.
3Lifespan of 2-3 Years
The typical lifespan is around 2 to 3 years, though this can vary with water temperature, water quality, and daily care. Prepare your setup with a long-term commitment in mind.
4Adult Size of 3-4 cm
Adults typically grow to about 3 to 4 cm in body length. Choose a tank or aquatic setup with enough room to comfortably house the fish once fully grown.
5Choosing Tankmates Carefully
The long fins carry some risk of being nipped or damaged by other fish. Opt for calm, gentle tankmates, or consider keeping them alone or only with others of the same variety.
6Avoid Sudden Water Changes
The aurora coloration and glitter are thought to be sensitive to water conditions. Change water gradually and avoid sharp swings in pH or temperature to help preserve their coloring.
7Build a Daily Observation Habit
Fin damage or changes in coloration can sometimes signal health issues. Get into the habit of checking swimming behavior and fin condition at the same time each day, such as during feeding.
