Ponyo Medaka
Ponyo is a medaka that pairs white, transparent scales and a rounded daruma body with protruding eyes that angle diagonally forward. Seen head-on, it seems to look right back at you, and the name comes from its resemblance to a film protagonist. It is considered a variety for intermediate keepers, since the body shape and eyes call for extra care, so it is best brought home once you are comfortable with basic medaka keeping. Reliable information on its lifespan is limited, so no figure is given here. Its small round body and expressive eyes make it a joy to watch.

Ponyo Medaka key facts
- Care level
- Intermediate
- Lifespan
- Few reliable data
- Size
- Shorter than normal-bodied medaka because of the daruma body (wild medaka reach up to 4 cm SL: FishBase)
- Diet
- Omnivore (floating prepared foods, live foods such as daphnia)
- Container & Tank
- Its forward-facing eyes are best enjoyed head-on, so a glass tank viewed from the side suits it.
- Breeding
- Fixation among memae fish is said to be 30-50%. Choose breeders with at least one forward-facing eye and exclude fish with crooked mouths.
- Health & Cautions
- Protruding eyes are easily injured, so avoid sharp décor and gravel; the daruma body also swims less strongly.
- Diet & Feeding
- Give floating food that is eaten within 3-5 minutes: at least twice a day in summer, once a day in spring and autumn, and little or none outdoors in winter.
- Cautions
- Never release ornamental medaka into rivers, ponds or paddies; hybridisation causes genetic pollution of wild medaka.
About Ponyo Medaka
Ponyo Medaka: white transparent scales, a rounded daruma body and forward-angled protruding eyes. Care level, name origin and what to know before you buy.
7 things to know before welcoming a Ponyo Medaka
1The Forward-Facing Eyes
Ponyo's defining feature is its protruding eyes angled diagonally forward. Combined with white transparent scales and a rounded daruma body, it seems to meet your gaze when viewed head-on. The name comes from its resemblance to a film protagonist.
2Why It Is Rated Intermediate
Ponyo is rated for intermediate keepers. Its daruma body and protruding eyes mean more points to watch in the setup and at feeding time than with a standard-bodied medaka. It is safer to bring one home after you have learned the basics of medaka keeping.
3Protecting the Eyes
Because the eyes protrude, keep sharp or rough decorations out of the tank. Favor plants and smooth materials, and handle the fish gently with a net during cleaning or moves. If the eyes look cloudy, damaged or otherwise different from usual, check the water quality and ask the breeder or an experienced keeper.
4Gentle Flow, Stable Water
A daruma body is thought to make swimming more tiring, so avoid strong currents and aim for a gentle flow. Change water in small amounts and never shift temperature or water quality abruptly.
5Feeding Tips
With a round body and eyes set differently from a standard medaka, Ponyo can take longer to spot and reach food. Offer small, easy-to-eat food in modest amounts and watch that each fish is actually eating. Remove leftovers promptly, since they can foul the water.
6Choose Tank Mates Carefully
Housed with quick, standard-bodied medaka, Ponyo may lose out in the competition for food. If you keep them together, watch each fish closely and consider separating them if some are not getting enough to eat.
7Acclimation and Preparation
Prepare the container and tank water before the fish arrives. On arrival, float the bag to match temperatures, then acclimate the fish to your water gradually before releasing it. Check the listing photos and description, and ask the breeder about anything that is unclear.
