Why is this variety called "Hakuto" (white rabbit)?

Its white body and red eyes give it a cute, rabbit-like look, which inspired the name Hakuto. It's one of the more visually distinctive improved medaka varieties.

Can beginners keep Hakuto?

Hakuto is generally considered an intermediate-level variety. Because of its albino traits, it needs a bit more care around lighting and water quality, so it's best attempted after some medaka-keeping experience.

Can Hakuto be kept with other medaka?

Yes, its calm temperament generally makes mixed-tank keeping possible. Since its white body stands out, though, it's worth monitoring how it interacts with tankmates.

Can Hakuto be kept outdoors?

Outdoor keeping is possible, but since its red eyes tend to be sensitive to light, providing some shade from direct sunlight is reassuring. Extra care is especially helpful during periods of strong sun.

Does Hakuto's color change as it grows?

Hakuto generally keeps its white coloring throughout its life, though individual variation and tank conditions can cause slight differences in shade. If you notice a sudden color change, it's worth checking water quality and overall health.

Hakuto

Hakuto is an eye-catching improved medaka variety, prized for the striking contrast between its clear white body and deep red eyes — a look often likened to a small white rabbit, which is exactly where its name comes from. Its pale coloring stands out beautifully against green aquatic plants, making it a popular choice among hobbyists. Hakuto tends to have a calm, easygoing temperament and mixes well with other medaka, though as an albino strain it can be a little more sensitive to bright light and shifts in water quality, which is why it's generally recommended for intermediate keepers. With a lifespan of 2 to 3 years and an adult size of roughly 3 to 4 cm, Hakuto rewards patient, attentive care.

7 things to know before welcoming a Hakuto

1Best for Intermediate Keepers
Hakuto is an albino variety, so maintaining its color and health takes a bit more know-how than standard strains. It's best suited to keepers who already have some medaka experience.
2Sensitive to Bright Light
Because albino eyes lack pigment, Hakuto can be more sensitive to strong direct sunlight or bright lighting. When keeping them outdoors, providing some shade helps protect their eyes.
3Calm and Tank-Mate Friendly
Hakuto has a gentle temperament and generally does well alongside other medaka without much conflict. That said, its bright white body stands out, so keep an eye out for any chasing from tankmates.
4Watch Water Quality Changes
While reasonably hardy, Hakuto can be sensitive to sudden changes in water quality. Change water gradually and avoid sharp swings in temperature or chemistry.
5Adult Size: 3–4 cm
Adults grow to about 3 to 4 cm. Choose a tank or container with enough room to avoid overcrowding as they mature.
6Lifespan of 2–3 Years
Hakuto typically lives around 2 to 3 years. Consistent water care and proper feeding help support a long, healthy life.
7Preparing Before Arrival
Before bringing Hakuto home, prepare your tank's water conditions in advance and plan for a slow acclimation process. Watch closely as it adjusts to its new environment.
